Hi SM users,
The problem:
Intermittently SM would grab 100% of cpu. This was on a 4 processor machine,
so /usr/bin/sar would show user-level cpu stepping up and down by 25%.
Sometimes reaching all 4 cpus (100%). Systems staff would usually have to
kill the runaway process ids on Monday morning. There was no obvious connection between times of start of cpu hogging and SM activity as logged
on httpd access or error logs, but there was usually SM activity at most a few
hours beforehand.
We know it was SM related because cpu hogging started the day it was installed, and ceased when SM was turned off for a week.
As open source advocates in an organization with Microsoft addicted system support department, this has proved to be quite an embarrassing episode.
Sandy,
Sorry no one had any ideas for you. I've never heard of this problem but would be interested to know if you were able to track it down.
