I got the OOM error, too. I had three rails applications with vendor
directories in my workspace. I ran a runtime-workspace and increased
memory to 512m which did not help, too (I added -Xmx512 to the VM
arguments, hope fully it really does what I expect). Only by closing one
of the rails projects I could finally get rid of the OOM error.
(Un-?)fortunately I can not reproduce the error with current HEAD
although I could not see any code change concerning the Indexer.
Well I'm hoping that this was an artifact of the problems in the
RubyModelCache that I mentioned earlier then since it cleared for you. I had
found memory problems/bugs there that I did fix. The Indexer just happened
to exercise the cache a lot so it unearthed the problem quickly.
The bug in question is that the RubyModelCache didn't have a specific cache
for ISourceFolderRoots (because until fairly recently we didn't even have
the notion of them). So they were getting thrown into a plain old HashMap,
and I believe holding onto all of their children. So we were effectively
storing all of the model in a HashMap that didn't overflow or clean up when
it approached the memory cap. There should have been a noticeable memory
difference between versions before my fix to the RubyModelCache file and
after.
Thanks,
Chris
