| Out of memory Errors with new VE [message #128247] |

Hi,
I am getting out of memory errors since I installed Visual Editor
available with Calisto. The memory consumption starts the moment I open up
a Visual Class file. There are times when the status bar hangs at the
message 'Starting up Remote VM' and after a while Eclipse throws a dialog
box complaining about the Out of Memory error. At other times, the out of
memory is thrown after I have worked with some Visual Classes for a while.
Looking at the memory consumption in Task Manager, the memory starts
increasing when a new visual class is opened and does not seem to go down.
My startup params are
eclipse -clean -vmargs -Xmx512M
My OS is Win 2003 Server sp1
JDK 1.5.0_06
Anybody seen similar issues?
Thanks
Aashish

Hi Rich,
I have Eclipse 3.2 with Web Tools(not yet using it), EMF, GEF, VE, and
dependencies installed.
Non-Eclipse provided plugins -
JADClipse (been using this for more than a year now),
Subclipse (subversion - using this since 3.1 with no problems)
Findbugs (been using for more than a year)
Omondo (installed this fresh with 3.2)
Sequence of events since last post -
Eclipse crashed after some time (~ one hour) of usage - became
unresponsive and disappeared.
Set max heap size to 1024M
Restarted Eclipse and closed all editors - memory was 190MB - normal in my
case.
Open a Visual Class - The 'Starting a remote VM message' went on for ~45
secs. the memory jumped to 286 at the end of it.
Opening additional visual classes increases it by a couple of megs (seems
normal).
The Visual Classes consist of approx 7 widgets on them ( text boxes,
combo, group, button, table, radio).
So far so good.
Thanks
Aashish

Just out of curiosity, can you try a brand new workspace? It may be that
there is something in your project's classpath that is big.
As for my tests, I have a Windows XP SP1, Eclipse 3.2, VE 1.2, EMF 2.2,
GEF 3.2.
When I first open the workspace, Windows TaskManager says 59Meg. I then
open one VE (just a JFrame subclass, nothing in it), and it jumps to
94Meg. Then I open another simple JFrame subclass and it jumps to 99Meg.

Does it happen if you increased to -Xmx1000M? Is it the main eclipse IDE
vm that is getting the error or is it the remote vm that is getting the
error?

Hi Rich,
It is the main IDE VM.
I can see the remote VM process in Task Manager with approximately 16MB,
which sounds normal to me.
However, the IDE VM has more than doubled (~180 to ~380) with just two
visual classes open.
I have not tried with 1000M. I'll try that but is that really necessary.
That sounds like a large number for a IDE process.
What are normal memory numbers for Visual Editor development?
Thanks
Regards,
Aashish

On our tests if we just have Eclipse, GEF, EMF, and VE installed we
usually don't exceed 100M. It may be that there is something else in
your system which brings it up near the max before VE even starts.
Unless maybe your VE classes are huge? If you created just a simple
little class without much in it does it still double in size to 360M?

Hi Rich,
Thanks. I'll try a new workspace.
In the meantime the IDE crashed again with an OutOfMemory error during the
message 'Starting Remote VM'. I had to kill the process as UI became
unresponsive after showing me the error dialog. Memory at the time of the
kill was 601MB.
Here are the abbreviated log entries -
!ENTRY org.eclipse.ve.java.core 4 16 2006-07-11 16:54:39.641

I also started having this error with 3.2 plus MyEclipse plus VE. It's
NOT regular heap space, it's "perm gen" which is apparently statically
allocated.
If you are using Sun Java, add -XX:MaxPermSize=128M to your eclipse.ini.
I had increased my -Xmx space up to 1500M and it still wasn't working.
Since I discovered this I now run great setting -Xmx to 650M.

Right, that PermGen error is the clue. That has been brought up
internally in my company often recently. Chas is giving the right answer
for that problem.
