Description Mary Ellen Foster 2007-11-21 13:38:02 UTC

Description of problem:
It's well known that Eclipse has difficulty with "PermGen" memory, and that you
need to increase the default size. /usr/share/eclipse/eclipse.ini contains
"--launcher.XXMaxPermSize 256m", which looks promising. However, that means that
the launcher is supposed to detect for itself whether it's running on a Sun VM
and increase the value in that case. It seems that only works on Windows (and
maybe even not there) -- see
http://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to_Eclipse%3F

I'd suggest putting this directly into the vmargs instead: adding
    -XX:MaxPermSize=256m
to the end of the file directly. I've just done this, and I hope that it'll
solve my PermGen issues ... I haven't tested it heavily yet, but I'm about to,
so I'll report back here if it keeps crashing.

Version-Release number of selected component (if applicable):
eclipse-platform-3.3.0-30.fc8

How reproducible:
Every time (eventually)

Steps to Reproduce:
1. Run Eclipse
2. Open lots of projects and do lots of edits, builds, etc
  
Actual results:
Eclipse runs out of PermGen space and either complains or crashes

Expected results:
Eclipse keeps working!

Comment 1 Mary Ellen Foster 2007-11-21 13:47:47 UTC

Okay, a bit more investigation makes me believe that eclipse doesn't actually
read eclipse.ini at all ... *is* there any way to get the needed extra vmarg to
Fedora Eclipse?

Comment 2 Andrew Overholt 2007-11-21 16:13:47 UTC

I tracked the problem down to the fact that Eclipse was looking for eclipse.ini
in %{_libdir}/eclipse and not %{_datadir}/eclipse where the file was.  Putting
it in the former shows the vmargs being passed through correctly in both the
Help->About->Configuration dialogue and in jconsole.

This fix will be included with 3.3.1.1 which I am going to push as soon as I
sort out the ppc64 build.
