Is the supervisor process causing performance issue on my PC?

Managed Services — Thu, 25 May 2006 10:02:59 GMT

I have having some reported problems regarding the overall performance of my machine. During investigations, I found the following process running since Apr 22. Could this be causing the problems? What does it do and can it be killed off?
The process appears as
root 1341 1 0 Apr 22 ? 1063:44 /opt/pd/lbin/supervisor mentor
any pointers would be appreciated?

Hi

This process is related to the lp scheduler and it should be a problem killing it, maybe you can stop & start the scheduler

Presumably you meant 'shouldn't be a problem'??

Also, is it preferable to use 'lpshut' rather than killing the 'supervisor' process?

Hi MS,
Hard to tell if it's causing a problem, but it is certainly using a fair amount of CPU. Does it show up in 'top' using a lot, too? Running 'glance' or 'tusc' may show what it's spending its time doing.

It is part of the HPDPS suite (but I don't know anything about that suite; it's fairly old and the man pages say "TO BE OBSOLETED" at the top). I think you can restart it using 'pdstartsuv'. 'man -k HPDPS' should list all the relevant commands.

Hope this is of some help.

Andrew

check lpstat -o for fairly old print jobs, maybe a network printer got unreachable. :)
