Tracking which Unix process pid just crashed


I got a monitoring alert that says a Unix process just crashed but the alert did not
specify the pid or process name that just crashed.

Is there any way to find out?

What about the directory /usr/ucb/... : does it hold any clue

I recall in Linux  /var/run   there are *.pid files that hold the pid of processes.
If a process was abrupted terminated or manually "killed", does the pid file
stays behind?  I thought of going thru one by one the .pid files to see the pid
& check which ones are no longer found in "ps -ef"

/var/log/messages did not give any clue

any good Shell script / command to check this easily would be most welcome
as well

What does the date stamp of those /var/run/*.pid files mean?
