dtrace discuss - Dec 2007 - monitoring a process

Hi All

Can someone please provide some pointers on a method to track a process. The
situation we have is an application process refuses to die, every time a kill is
issued the process respawns itself. At present the server is rebooted to remove
the process, which is not ideal. I need to identify what the process is doing
what it is referencing etc basically find a root cause to the problem. Can
dtrace help with this analysis, if it can what scripts or probes do i require.

Thanks

I''d start by running ''ptree'' on the process in
question and having a
look at its ancestors. What signal are you sending with
''kill''? If the
process reappears following a SIGKILL then run ''ptree'' to
identify its
parent.

Hi Robert 

I am providing a kill -9 to the process
