looks like having a performance issue on the server, first make sure that you have the latest service packs installed second can you tell me your HW config.

guys finally got a solution now by myself.

the problem was antivirus installed which was killing the nspi threads to GC from the mailbox server
and that was causing mad.exe causing the high cpu utilization.
Once is removed the antivirus all problem resolved.

Thanks anyways guys.
