oracle - ORA-24550: signal received: [si_signo=6] error -


i want know ora-24550: signal received: [si_signo=6] means?

i know oracle error , may oracle latest patch can solve issue.

when error triggered, scenario signal has handled or whether error occur when application has handle related oracle , application failed that.

this sign oracle client has received signal wasn't expecting. oracle docs say:

ora-24550: unhandled signal #number received. string

cause: serious error: signal received

action: refer platform-specific signal code, , see if application code caused error. otherwise, record error state , notify oracle support services.

by default, oracle registers own signal handlers, you can configure let signals propagate instead.

you see log line this:

ora-24550: signal received: [si_signo=6] [si_errno=0] [si_code=1] [si_int=597680428] [si_ptr=0x239fe290] [si_addr=0x3f445c43c0]

and may see traceback too.

to debug, need find out producing signal. si_signo=6 means you're getting signal 6. can find out signal $ man 7 signal:

standard signals

signal     value     action   comment ------------------------------------------------------------------------- sighup        1       term    hangup detected on controlling terminal                               or death of controlling process sigint        2       term    interrupt keyboard sigquit       3       core    quit keyboard sigill        4       core    illegal instruction sigabrt       6       core    abort signal abort(3) sigfpe        8       core    floating point exception sigkill       9       term    kill signal sigsegv      11       core    invalid memory reference sigpipe      13       term    broken pipe: write pipe no readers sigalrm      14       term    timer signal alarm(2) sigterm      15       term    termination signal

we can see you're getting sigabrt. means something calling abort().
