Core file created with wrong pid number

acanady · 11-30-2011, 03:12 PM

Running SuSE 10.3 on IBM z10.
For some core file names we notice the number that should correspond to the PID is not correct. In /etc/sysctl.conf
kernel.core_pattern = /temp/core/core.%p.%t.%e

For example, running a test using the command
sleep 60 &
and then running kill -11 I get
core.32363.1322665189.ksh
where 32363 is the correct PID.

However, for a java process running under WebSphere I get
core.7863.1322663364.java
where 7863 is NOT the correct PID.

Any idea why?

Is it possible what you killed was a thread rather than a process and that the PID you're seeing is the PID of the first thread rather than the one you killed?
