Title: Help with strange process
Post by: jim7jim on May 21, 2010, 07:25:56 PM

Server locked up 4 times with kernel panic 3 days ago. After running memory / hardware diagnostics and finding no problems, I've been watching processes and looking in the logs for possible clues. No lockups for the last 3 days.

Anyway, I have a process that's been running for 13 hours that looks strange (to me anyway). Under Command (from htop):

runsvdir -P /service log: pervise/lock: temporary failure runsv mysqld: fatal: unable to lock supervise/lock: temporary failure runsv oidentd: fatal: unable to lock supervise/lock : temporary failure runsv httpd-admin: fatal: unable to lo

Then the 'Command' text gets cut off. Does anyone know what this service might be and if it indicates a problem?

runsvdir is the master process responsible for all supervised services, of which there are many in SME server. You should expect to see a single instance of it running always.

What you see under 'Command' are error messages from the 'runsv' processes that 'runsvdir' starts. You show multiple runsv processes unable to lock a file - that's likely because you are trying to start 'runsv' where one is already running. The error messages certainly indicate a problem - perhaps you, or someone/something, killed the original runsvdir process.

I suggest that you reboot the system. If you see any error messages in the runsvdir process table entry after reboot, then open a bug report.

If you see any more kernel panics, open a bug report.

Rebooted. No error messages so far.

Thanks Charlie.
