Constant "PermGen space" crashes in Helios: what is this? [message #545806] Fri, 09 July 2010 08:34 Go to next message

Today I suddenly started to get constant crashes in Helios. Every 5
minutes or so I suddenly get a popup that reads:

--------------------------
Unhandled event loop exception
PermGen space
--------------------------

and then the application terminates. Any idea what that means or what
might be causing this? It is getting totally unusable!

I closed and deleted the project and then re-imported it. Since then
these "PermGen space" crashes have stopped, but now almost any file
operation (opening a file, closing it, renaming it, etc. ) becomes
extremely slow and every second time Helios crashes (i.e. just
disappears) in the process. This is getting nightmare!

I am also experiencing PermGen errors. I have increased the permgen space to 256m (and even to 512m) per the FAQ and it still crashes.

This is Helios (JEE developer distribution) with JDK1.6.0_21 on Windows XP 32-bit.

The workspace log pane has several "Unhandled event loop exception" messages with a stack trace of "java.lang.OutOfMemoryError: PermGen space" followed by another "Unhandled event loop exception" with a stacktrace value of "An exception stack trace is not available."

Shutting down eclipse (when it works -- usually I have to kill the process) usually gives me a message of "Internal Error PermGen Space."

I can easily reproduce this if anyone can think of any other useful information that I could provide.

The .metadata/.log file has this:

!ENTRY org.eclipse.ui.ide 4 1 2010-07-09 16:43:04.500
!MESSAGE Problems occurred while trying to save the state of the workbench.

I have the same problem since updating the jdk to 1.6.0_21. In my
opinion Oracle has changed the jdk so that the eclipse launcher
doesn't recognize it anymore as Sun VM.

Workaround: Start eclipse from the command line and pass the
PermGenSpace parameter:
eclipse.exe -vmargs -XX:MaxPermSize=256m

Yes, with

also updated the three space parms from 256K to 512K

You want tell 512m? if not, that is the reason

Otherwise, double-check that you have your eclipse.ini with no errors.

Sorry, it was 512M. Afraid I am somewhat of a newbie, is there a tool to validate eclipse.ini or to "double check" should I just eyeball it.

Additional info: eclipse starts fine, but when I try to import a maven project/pom, I get the Perm-Gen error. I am using m2eclipse.

Olaf is correct, the launcher is looking for a vendor "Sun Microsystems",
which is now "Oracle".

As a side note, it is better to add the -XX:MaxPermSize=256m in the
eclipse.ini file after the -vmargs line because specifying vm arguments on
the command line override the vm arguments in the .ini file.

Hi!!
Does it work??
I have the same problem.
I increased the PermGen space in the eclipse.ini file on 512m, but nothing happen.
I use the same eclipse version and the same java version as the user above.
I have a new bigger problem. I pressed the "run"-button and there comes a massage that this function isn't available.
Do someone know how I can solve these both problems??

Thanks
jared.

A workmate has the b07, but I don't know where I can download this b07. He hasn't any problem, but I have.
Do someone know where I can download the java version b07??

The following error message comes because the jdk 1.6.0_21 b06 has a bug, right??

Can Eclipse produce the error message above or does the error message only come if there is a bug in the jdk??

thanks.

Jared,

Eclipse has a known compatibility problem with b06. You should get 1.6.0_21 b07 build or apply the workaround detailed in multiple places.

Thanks. I thought that there isn't any b07 version to download, but at home I try to download this version and it was a b07. I thought this, because on the download page they wrote about the b06 version.

It works. I'm happy.

Thanks for your efforts.

So I have this same issue. This thread has been very helpful. Thanks to the poster and contributors!

I assume the JDK b07 requires the JDK, JRE, and debug jars; is that correct?

I am at my wits end on this crazy project. 17 steps deep on the dependencies and now I have to go back and change java itself. Madness. I was ready to call Helios Eclipse "collapse" as a rude nickname.

Sad

Incidentally, I installed the JDK 7 b10 which was the only 7 build on the referenced download page. Still within seconds I got a permgen space error. I have also modified my eclipse.ini file as recommended above, also to no avail.

I have no idea what might be wrong.

You installed jdk 7. Eclipse doesn't yet support jdk 7. You need to download jdk 6. Go get the latest jdk 6 from java.sun.com. Be sure to pick the jdk not the jre. Run the installation to install it on your system. Point the eclipse.ini to the javaw.exe file in the bin directory.

OK I went back and installed jdk 6. Unfortunatly the latest JDK I can find on the site tests as b06. If b07 exists I haven't founf it. I've found numerous references to it everywhere but on the Oracle site. Any ideas?

OK so I found the correct download for the b07. It's the Windows JRE ONLY so some of the info in this thread is misleading.

Then of course, my JVM will not start. The only java dependent application not working at all now on my machine is eclipse.

Now what?

Any advice on this issue?

The JDK on the oracle download site (java.sun.com) does contain the b07 version. I just downloaded it and installed it.

Are you specifying the vm as either a command line argument with -vm {path to jdk}/bin/javaw.exe on the command line or including the vm definition in your eclipse.ini.

If not, you may have path problems that are causing a different vm to be run instead of the one you think is running.

If you can't get the b07 JDK installed, then follow one of the other work arounds documented in the sticky post at the top of the forum.

Ah, many thanks. I am relatively new to the eclipse / java world. Thanks for your help. I have no idea what VM the thing was looking for because as far as I know its the only one on my machine. I always uninstall before I install so ....


Regardless it works so TYVM!

If I want to change the eclipse.ini file, have I only insert the following line??
-vm {path to javaw.exe}\jdk\bin\javaw.exe

Should I use "..." or '...' for the path??

Thanks.

Im running into the PermGen space issue even after adding the ini settings. My ini file is as follows:

-Xms512m
-Xmx512m
-XX:MaxPermSize=256m

However, Ive tried most ever configuration of heap Xms, Xmx and XX:MaxPermSize.

The issue for me seems to be especially common when I try and run a Birt report from within Eclipse.

Im running jdk 1.6.0_21 and Eclipse Version: Helios Service Release 1
Build id: 20100917-0705

Is there anything else I can try except altering the ini settings?

Sorry, I posted the wrong version. I am running :

java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)

However the error still occurs. As soon as I starting running Birt reports I get the following error (or similar):

SEVERE: Error processing request
java.lang.OutOfMemoryError: PermGen space

What I found helpful was to downgrade jvm. I don't know how to use eclipse.ini, so I use

eclipse.exe -vm "c:\program files\java\jdk1.6.0_10\bin"


to run Helios (Windows platform, as you can see). Running JDK1.6.0_10, everything started to work fine, which was great as I urgently needed to make Helios work for school.

That isn't the correct format for specifying the jvm on the command
line. You need to point to the actual executable. It should be c:
\program files\java\jdk1.6.0_10\bin\javaw.exe

I was able to resolve the "permgen space" errors that I was getting by making the following changes (after also making the changes to the .ini specified in this thread):

In "Run Configurations" > "Apache Tomcat"

If you click on the "Arguments" tab then add the following to the VM arguments:

-Xmx1024m -XX:MaxPermSize=256M.

Since I added this I haven't had any issues running Helios on JDK1.6.0_22.

Hope this helps.

Iain

Hi, well for a reason I still don't know. The parameters given to the eclipse.ini are not taken. So I'm using java commands directly to execute the eclipse with the specific parameters.

Here is a solution that at least interrupt the constant crashing of eclipse.

Command format: java [ options ] -jar file.jar [ argument ... ]

Examples:
java -XX:PermSize=64M -XX:MaxPermSize=256M -Xms512M -Xmx1024M -jar <ECLIPSE_HOME>/plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar (for eclipse 3.5.x)
java -XX:PermSize=64M -XX:MaxPermSize=256M -Xms512M -Xmx1024M -jar <ECLIPSE_HOME>/plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar (for eclipse 3.6.x)

Best Regards,

I got into this age old problem of "permgen space" issue, whenever I was opening up a JSP or XML file. And as members have posted, my eclipse indigo 3.7, was not picking up permgen settings. The neatest way that I could make it work was to introduce -XX:MaxPermSize=512m after -vmargs

my eclipse.ini looks like:

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.100.v20110502
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
--launcher.defaultAction
openFile
-vmargs
-XX:MaxPermSize=512m
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx4192m


Hope this helps someone!
