High CPU utilization on AIX 7.1 (IBM license monitor utility)
« on: September 13, 2017, 07:58:59 AM »
I'm curious to know if anyone else has had problems on their CMOD server where the IBM licensing scan utility "wscanfs" has been consuming high amounts of CPU?  I am seeing this utility constantly running at above 30% CPU.  I have a number of other AIX 7.1 servers, but this production CMOD server is the only one that this is happening on.  I don't believe this is directly related to CMOD, but I have been after IBM for a resolution since January and I didn't know if anyone else is seeing issues.

Hey Dave.

I would normally kill and restart a misbehaving process.  Does the problem go away if you bounce arssockd?

I can have this service killed almost every day, but it comes back during the nightly TSM backup cycle.  It is part of Our Tivoli/BigFix implementation that IBM uses to monitor license product capacity.  My guess is it is crawling the OD repository even though we have told them to exclude this file system.

I didn't really expect any solutions here, I was just wondering if anyone else has seen a similar issue.

Thanks.

Yeah, if this is some sort of inventory tool, it might be reading every individual file, then doing some work on each file to determine if it matches what it's looking for -- and if it ends up searching the caches, yeah...  it'll be doing that for a looooong time.

I'd double-check the configuration to see if you've typo'd the cache filesystems or something.  Otherwise, you'll need to start harassing IBM regularly.
