Warning: PBS Professional has detected core file(s) in PBS_HOME that require attention!

I see this warning in my log files, but I can’t see any obvious documentation on what it means?

Warning: PBS Professional has detected core file(s) in PBS_HOME that require attention!!!

There should be a core dump file present in your PBS_HOME directory.
Please move that core* file(s) to some other location or delete it and restart PBS services, then you should not be seeing that message again.

Hey @datakid
Before you delete the cores, could you do you give me a little bit of information about them?

  1. Find the cores. They’ll be in one of the priv directories in pbs home (e.g. /var/spool/pbs/server_priv).
  2. do file . This will tell you what daemon crashed. It’ll likely be the same daemon of the priv directory you are in.
  3. do: gdb /opt/pbs/sbin/ /var/spool/pbs//core
  4. do ‘bt’ and post the output to the thread.

This will help us debug what happened and possibly fix a bug.

Thanks,
Bhroam

Thanks for the info. I’ll file a bug for this. What version are you running?

Bhroam

[user@clive pbs]# pbsrun --version
pbs_version = 19.1.3

Thanks for the reply. I’ve filed the ticket. It may already be fixed in master. There has been many bugs fixed in master since 19.1.3 was released.

The server crashed when trying to save to the database. I’m not the expert of the database, so I’ll have to let someone else jump in.
