As you are running this within an infinite loop ("for (;;)"), the GC will probably never be allowed a chance to run and therefore the OOM error. Also, the fact that explicitely invoking GC seems to work around the issue makes me suggests that this may be an invalid report: it hints that the thing is being garbage collected, maybe just not fast enough. On the other hand, you may not have tested this enough (more than one hour may not have been enough). I'd suggest making a few experiments (leaving the test application run overnight, using the verbose GC switches [1], etc.) and report results back. There's an interesting article [1] on GC tuning you may be interested in. ;-) [1] http://www.petefreitag.com/articles/gctuning/ -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
