hostAgent process using 99% of 1 processor - why?

[Mott Given]

We have what looks like a runaway process on an N4000 8-way machine running HP-UX v11.11.
The runaway command is "hostAgent", run by root and using 99% of one processor. Grepping for the process shows that it is run as:
/opt/storability/bin/hostAgent -w /opt/storability/bin -msgdir

What does it indicate that this process is using so much CPU time?

Well, it indicates that the process is working very hard on something. Find it's pid by:
ps -ef | grep hostAgent | grep -v grep
or
probably you saw the pid in top.

After this:
tusc -p

In tusc you will see the system calls used by this process and you'll get a general idea why it's working so hard.


BTW, did you thought about restarting it? Sometimes it helps.

This process is part of SDM(storage device manager). Do you have some gui/tui session open for SAN management?? You can stop and start it.
