I do not pretend it is the same problem, it might just be related.
But the only easy way for me to reproduce it is just compiling jacorb
(www.jacorb.org) on releng_6 (about ten days old) using libthr : after
a while java hangs (can only be killed by -9) and 'top -H' shows three
threads each taking 70-90% CPU-time.
If I take a 'gcore' snapshot of it (dunno how trustful that is)
it shows all threads in _thr_umtx_wait() (script-log attached).
But :
- only 2x2 smp-amd64 releng_6, 1x2 smp goes OK
- only easy to produce when using optimized VM (I'll retry
harder to produce a hang with java_g)
- no prob on releng_7 (2x2 smp included) for this test
This is thin, but all I have for now ...
Thanx, Arno
