      Received my first panic code on a process, resulting in its shutdown. I’ve transferred the process log file and have the panic code with resulting debug info. However, I am unable to make heads or tails of what this is telling me.

      Here is the panic code:

      PC = 0xea01280

      I’m attaching the log file as well. If anyone can help me understand what this means, I would appreciate it.

          I think PC is program counter.  That’s the memory address of the instruction that was being processed when the panic occurred.  The actual cause of the error was “thread 1 received signal 10”.  If you type “kill -l” you can see that signal 10 is SIGUSR1.  Here’s an article that describes what SIGUSR1 is used for:

          <a href="http://en.wikipedia.org/wiki/SIGUSR1_and_SIGUSR2&#8243; class=”bbcode_url”>http://en.wikipedia.org/wiki/SIGUSR1_and_SIGUSR2

          I would guess that this was caused by a Cloverleaf bug.

            David thanks for sharing the “kill -l” which I had never done.

            Perhaps I can use it some day to help figure out a problem.

            We are on AIX 5.3 and our displayed SIG codes via “kill -l” seems to be different from what you described, so I wasn’t sure if SIG codes are platform dependent.

            Here is what “kill -l” gives on our platofrm and it seems code 30 is the one for USR1 while code 10 is for BUS, if I read this right.

            Code:

            1) HUP
            2) INT
            3) QUIT
            4) ILL
            5) TRAP
            6) ABRT
            7) EMT
            8) FPE
            9) KILL
            10) BUS
            11) SEGV
            12) SYS
            13) PIPE
            14) ALRM
            15) TERM
            16) URG
            17) STOP
            18) TSTP
            19) CONT
            20) CHLD
            21) TTIN
            22) TTOU
            23) IO
            24) XCPU
            25) XFSZ
            26) bad trap
            27) MSG
            28) WINCH
            29) PWR
            30) USR1
            31) USR2
            32) PROF
            33) DANGER
            34) VTALRM
            35) MIGRATE
            36) PRE
            37) VIRT
            38) ALRM1
            39) WAITING
            40) bad trap
            41) bad trap
            42) bad trap
            43) bad trap
            44) bad trap
