The stack here is mostly irrelevant, but there’s a good chance this is
one of several leaks fixed in JRuby 1.2. Can you give RC2 a try? We’ve
heard from others who saw leaks and memory issues go away in 1.2.

we were on trunk since trunk has the solaris getpwuid fix so we cant
use 1.2.0RC2. We were having a few issues with trunk though so went
back to 1.1.6 util 1.2.0 is out and stable. Not to say 1.2.0 is not
stable, we were just seeing some errors in the app and wanted to
remove 1.2.0 as a variable.

When is 1.2.0 final slated for ?

Monday barring any newly discovered blockers…
