Re: OMS - strange behaviour of JRE process

Sorry,

Solaris 8, SPARC
This is a fragment of dump trace, generated by truss on the hanged jre process:

lwp_kill(8, SIGABRT) = 0
sigprocmask(SIG_SETMASK, 0xF57EF7E0, 0x00000000) = 0 sigprocmask(SIG_SETMASK, 0xFF178CE0, 0xF57EF770) = 0 lwp_kill(8, SIGABRT) = 0
sigprocmask(SIG_SETMASK, 0xF57EF770, 0x00000000) = 0 sigprocmask(SIG_SETMASK, 0xFF178CE0, 0xF57EF818) = 0 lwp_kill(8, SIGABRT) = 0
sigprocmask(SIG_SETMASK, 0xF57EF818, 0x00000000) = 0 sigaction(SIGABRT, 0xF57EF810, 0xF57EF910) = 0 sigprocmask(SIG_SETMASK, 0xFF178CE0, 0xF57EF7E0) = 0 lwp_kill(8, SIGABRT) = 0
