Question about CPU Switchover
I'm not sure if 1 problem process can cause this much trouble??? Other users were trying to generate reports but were blocked the way this job queue was setup (jobs waiting on queue).

Re: Question about CPU Switchover
More than likely your Lawson query had it's own issue and hung. Depending on the Lawson application, the queue may act in a FIFO methodology (first in first out), so if the guy at the front of the line is hung....everyone behind him sits and waits.
Talk to the Lawson Administrator and see if that person, or a DBA can kill the hung/stuck query. If the others begin to run...then that's the answer.
Someone should however identify the query/report request that caused the issue and fix it, prior to killing it. Or you're just going to hit this again.
Just a thought,
Rita

Re: Question about CPU Switchover
This isn't a problem. Why are you worried?
Unless you use threads, a process can only use one CPU at a time.
