Professional server 100% CPU usage.
Please Login to Remove!
We have Blackberry professional software for Microsoft exchange (10 cals in use) version 4.1.4(bundle 183). Server is running windows SBS 2003.
BB server software is pushing CPU usage to 100% and preventing other apps and services for running correctly.
I've stopped the MDS connection service (as we don't use this functionality) and this reduced CPU usage to normal for a while.
We again got a 100% CPU usage. It was found stopping the Attachment service reduced usage to normal I adjust the attachment setting to reduce load(only allow small attachments to be open and reduced number of threads used) restarted the service and tested was fine for a while. This morning had the CPU usage go to a 100% again. Stop the service and CPU load returned to normal. This lasted a few hours and then we started having issues again 100% continues load for extended periods I have stopped the BB server software completely(stop the server in BB manager and stopped all services).
Only CPU usage seems to be an issue, disc access and ram usage drops to near 0 once the CPU starts getting hammered and don't build up beyond normal in the lead up to the issue.
Any ideas?
I'm taking the server down tonight to run some more checks to make sure it isn't a conflict with another service that is causing the issue.
