I made the mistake of including too many search criteria into an "All Mailboxes" discovery search. Since I started the search yesterday msftesql.exe has been running at 80% utilization even though the search officially "timed out." Reboot did not solve the problem.
How do I kill this rogue search? I'm unable to stop it via the /ecp reporting tab because as far as its concerned the search has timed out and died.
