Just a note that I also see Out-of-memory errors from eclipse, during development, once in a while with M6.
I never got these before.

You can use Eclipse Memory Analyzer to dig deeper Marc. Just configure the VM to dump its memory image when OOM occurs and the tool will let you figure out where the memory's gone.

I've only seen this when running the cdt m6 tests using releng.  Our group here have been using platform m6 + cdt 7.0m6 for some time now without issue so far. (Though we have pretty big projects so run Eclipse with a 768M heap by default...)

Cheers,
James

Thanks John.

However the build is now running out of memory during JUnit testing (see details below). Has anyone run into this before?


Having merged up to 3.6m6 I noticed our headless test runs falling over intermittently with a permgen OOM on a Sun VM.  Perhaps we were just close to the edge before?

The CDescriptorOldTests haven't changed since 6.0... I presume you're still building against the m6 platform?

Does bumping the vm memory limit a little help?

Cheers,
James

I've added the new feature

   /cvsroot/tools/org.eclipse.cdt/all/org.eclipse.cdt.gdb-feature

to encapsulate the two new common gdb plugins, and have hopefully
updated all the necessary files to establish the proper build-time
dependencies.

John
