automountd using 100% cpu on a rx2620 server with Hp-UX 11.23

I have an rx2620 2-way server running HP-UX 11.23. The automountd process is taking up one full cpu all the time. Anybody seen this kind of behavior before? Is there a fix for this?

Hi,

I've never seen this before, but the first thing I would do is send the running process a SIGUSR2 signal, as that will turn on full debug logging to the file: /var/adm/automountd.log. This logfile will tell you exactly what the automountd daemon is spending its time doing.

Once the automountd has written a few seconds of data to the log file (maybe 15 seconds) send the automountd another SIGUSR2 signal (kill -17 ) and this will turn debug logging off again.

Once you look at the logfile you'll hopefully be able to determine what is causing automountd to take up all the CPU time.

Regards,

Dave

Hi Dave,

I did as you suggested, still nothing logged to that file. Automountd still using one full CPU. I am going to look to see whether there is any specific patches are out there for this problem.

Thanks,
