javax.sip.TransactionUnavailableException: Transaction not available --
could not acquire stack lock
http://code.google.com/p/sipservlets/issues/detail?id=280
I am doing a some simple load testing using sipp 50calls/sec, but the
server throws a lot javax.sip.TransactionUnavailableException: Transaction
not available -- could not acquire stack lock error
The load test script:
sipp $HOST -sf $1 -inf userIds.csv -m 90000 -r 100 -trace_err -l 1000
-skip_rlim
MSS-JBOSS: 1.7.0 on JBoss5

What else should I look? If I upgrade to 3.0 on JBoss 7, does it help?
Thanks lot.
