Eclipse 3.0: 100% CPU all the time [message #85031]

I tried various builds of the 3.0 line (3.0M1, 3.0M2, i20030723 and
i20030806) and they all have this same problem for me: even when I am
no longer using Eclipse (and it's iconified), it keeps my CPU at 100%
with a javaw process.

I use 2.1.1 every day and I never see this problem.

Has anyone else seen this?

Can you file a bug report with this? Please specify the platform
(windows, linux..) you're working on.

A way to find out what's going on is to start eclipse from the command
line with
java Xmx512M -cp startup.jar org.eclipse.core.launcher.Main -update
-application org.eclipse.ui.workbench -data c:\workspaces\eclipse-testpass

and use CTRL break to see a stack trace of all threads currently running
(that's under windows, not sure if this works the same way for linux)

I get a somewhat similar problem, both with 3.0M2, and 3.0I20030806.
Eclipse will perform normally for a while. Then it gets into a state
where on some operations (Ctrl-Shift-T, find type is one that seems to
trigger it a lot), it will basically just freeze for anywhere from 30
seconds to a couple of minutes. During this time, the cpu usage is
almost 100%. Once it starts doing this for Ctrl-Shift-T, it will always
keep doing it, until I exit and come back in. There are also other
operations which seem to cause the freeze, but Ctrl-Shift-T is the most
common one. There also seems to be the same pause on exiting Eclipse
sometimes, except in that case it sometimes never exits at all, and I
have to kill it.

One consideration is that I installed this version of Eclipse to use a
workspace from a 2.1.1 installation, ie I did not start from scratch. I
did this since I have a lot of projects in the workspace, and it is such
an incredible pain to import a larger number of existing projects form
the filesystem. Once a new Integration build is out I will perhaps try a
clean install, where I start with an empty workspace, and go through the
normal import process.

Okay, after a few hours, I got Eclipse to do the same thing again. I
included a full thread dump below and a quick look shows that only the
following thread is potentially busy at this point:

"Thread-8" prio=7 tid=0x272DA7F0 nid=0xcbc runnable [2872f000..2872fd8c]
at
org.eclipse.core.internal.properties.StoreKey.readNullTermin ated(StoreKey.java:140)

All the others are Object.wait() or Thread.sleep().

I tried to look up the source myself but I didn't find any
org/eclipse/core/internal/resources directory at
http://dev.eclipse.org/viewcvs/index.cgi/. I suppose I am looking at
the wrong tree.

I am using i20030806.

Any idea what's going on?

Okay, after a few hours, I got Eclipse to do the same thing again. I
included a full thread dump below and a quick look shows that only the
following thread is potentially busy at this point:

All the others are Object.wait() or Thread.sleep().

I tried to look up the source myself but I didn't find any
org/eclipse/core/internal/resources directory at
http://dev.eclipse.org/viewcvs/index.cgi/. I suppose I am looking at
the wrong tree.

I am using i20030806.

Any idea what's going on?

I'm having a similar problem, but I wasn't sure that is was Eclipse. Eclipse
will just become unresponsive. The problem is that I don't see any specific
pattern to this. I've also noticed Eclipse takes a considerable amount of
time to start up, now between 18 and 20 seconds. I using these options
C:\eclipse\eclipse.exe -data c:/work -vmargs -Xmx256M. I'm not sure, if
Eclipse is at 100% CPU utilization. I've never bother check. I have gotten
the Windows "Program is not responding" error. I find that if I kill Eclipse
and start up again it works normally.

Regards,

Jeff Duska
