FreeBSD 7.0-BETA3 JDK16 libthr crash

Tue Nov 27 02:33:52 PST 2007

Whilst testing a java webapp initially with an embedded jetty and then
running within tomcat (www/tomcat6) I seem to be reapeatedly able to
crash java with a signal 6 related to libthr. This is all running on
7.0-BETA3 with SCHED_ULE on a HP DL360 G5 with 2x Xeon E5320 (Quad core)
and 4GB ram.

I found the following error in tomcat 6 steddr.log:
Fatal error 'mutex is on list' at line 359 in file
/usr/src/lib/libthr/thread/thr_mutex.c (errno = 60) 

Java version:
# java -version
java version "1.6.0_03-p3" Java(TM) SE Runtime Environment (build
1.6.0_03-p3-root_22_nov_2007_15_55-b00)
Java HotSpot(TM) 64-Bit Server VM (build
1.6.0_03-p3-root_22_nov_2007_15_55-b00, mixed mode) 

Backtrace from the crash attached.

Any assistance in solving this would be appreciated.

Thanks in advance,
Andrew
