Quite possible.
And it also seems that JAMES does not properly recover from the OOM, since I
was able to log into RemoteManager, run memstat -gc, see 100MB free, and yet
the SMTP threads were all blocked.
seems strange to me.
did you look into potential multi-CPU problems yet? maybe it'd be
worth to dig into this a little more:
- you could force James to run on a single CPU only, if system load
allows it (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6378421
has some indications how this could be done)
maybe you are experiencing weird concurrency problems/race conditions.
- did you optimize the GC strategy? maybe it could help to explicitly
disable ParallelGC.
Anyone sucessfully running 2.3 on multi-CPU?
Bernd
