this looks like what I get with 7.0-BETA3 with SCHED_ULE on
a 2x Opteron 285 (Dual core) with my own java program :
Fatal error 'mutex is on list' at line 432 in file /files/bsd/src7/lib/libthr/thread/thr_mutex.c (errno = 0)
I use jdk15 :
java version "1.5.0_13-p7"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-p7-toor_16_nov_2007_16_38)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_13-p7-toor_16_nov_2007_16_38, mixed mode)
I play with
options SCHED_ULE
options IPI_PREEMPTION
options NO_ADAPTIVE_MUTEXES
but no combination "just works" (and only SCHED_ULE gives for now
the above error). The same program does "just work" on [67]-stable
UP and mono-processor dual-core; always jdk15.
FYI
Best, Arno
