How to force core dump of a process
Post 302193071 by Un1xNewb1e on Thursday 8th of May 2008 12:00:54 PM

The problem is only happening in Prod. Tracing is out of the question.
I did the following:
$ ulimit -c 9999999999 ## set core file size to unlimited
$ kill -s SIGSEGV <PID> ## Is this how a signal is sent to a PID??
The process terminates and no core files are created.
Is it required that the application has to be built/coded specifically to accept signals?
TIA.

abort
abort(3C) abort(3C) NAME
abort() - generate a software abort fault SYNOPSIS
DESCRIPTION
first closes all open files, streams, directory streams, and message catalogue descriptors, if possible, then causes the signal to be sent to the calling process. This may cause a core dump to be generated (see signal(2)). If the signal is caught, the handling function is executed. If the handling function returns, the action for is then reset to and the sig- nal is sent again to the process to ensure that it terminates. RETURN VALUE
does not return. ERRORS
No errors are defined. APPLICATION USAGE
is not intended to be caught. DIAGNOSTICS
If is neither caught nor ignored, and the current directory is writable, a core dump is produced and the message is written by the shell. SEE ALSO
adb(1), exit(2), kill(2), signal(2), signal(5), thread_safety(5). STANDARDS CONFORMANCE
