Description Andrew Overholt 2007-01-04 18:12:30 UTC

Description of problem:
Often times, when running Eclipse in FC6, I get OOMs from gij.  I don't know how
we can track this down, but it seems to be pretty reproducible.  I've had this
happen on both x86 and x86_64.

Version-Release number of selected component (if applicable):
gcc-4.1.1-30

How reproducible:
Seemingly random.

Steps to Reproduce:
1. Start Eclipse (eclipse) in FC6 from the command line
2. Work (try some Java projects, check out some Eclipse plugins, etc.)
3. Hope for an OOM

Actual results:
GC Warning: Out of Memory!  Returning NIL!

Expected results:
No errors, no OOMs.

I'm seeing out of memory errors thrown by libgcj when
running eclipse (eg, updating Classpath) using the gcj-eclipse RPMs.
I don't seem to have debuginfo so the stack traces for libgcj
are missing.

Comment 3 Tom Tromey 2007-02-17 00:40:53 UTC

In my case I already have a classpath checkout, so I choose
Team->Update or whatever that is called.

You can probably reproduce the OOM by following the
classpath-in-eclipse instructions

Comment 4 Andrew Haley 2007-02-19 13:14:34 UTC

I've tried to use those instructions, but I couldn't do anything.

The build runs for a while and then halts with an error.  Unfortunately, it
clears the Console window so I can't see what the error was.

I'd love to get to the bottom of this one, but as far as I can see it's
unreproducible.

Comment 5 Andrew Haley 2007-02-19 13:53:29 UTC

OK, I fixed that one, but I still can't get OOM.

When you find a way do do this that is reproducible, I'll have another look.
