Just an FYI;
After installing SP2 the CPU on my Orion SL2000 server was getting hammered by the SWJobEngineWorker.exe process
Using Orion Service Manager, I did a stop everything and then a start everything.
This same process took off again in a minute or two.
I then did a stop on the Solarwinds Job Engine only.
After the restart, it was fine for about 10 minutes, but it has taken off again.
YMMV
PS, all Wireless Controllers have disappeared in the Wireless Summary View as well.
