Description Juan Cervera CLA 2003-02-25 04:46:48 EST 
Hi,
I've been using Eclipse since v2.0. I'm using now M5. Sometimes it keeps on 
giving the following error when building and I need to restart Eclipse:
    java.lang.OutOfMemoryError

I'm running a big project with around 4,200 files. I have 512 MB and 100 MB of 
it are still free. Looking at the Task Manager it says the the Eclipse javaw is 
taking 108 MB of memory.

This problem seemed to be reduced when I was running M4 but seems to be back 
with M5.
I'm not sure if this is a configuration issue or a bug in Eclipse.

What arguments are you using when running eclipse executable ?

You can tell the Java VM to use more memory, typically we use:
-vmargs -Xms100Mb -Xmx250Mb
