When you attempt to expand or refresh Current Activity in the SQL Enterprise Manager, you may receive this error message:
Error 1222: Lock Request time out period exceeded
A refresh of Current Activity calls the sp_MSset_current_activity stored procedure. In the definition of the stored procedure, the lock_timeout variable is set as 5000 milliseconds (ms) first. Then, two global temporary tables are created, which issue an IX locks on the table level and X locks on the Key level against these system tables:
A second refresh usually results in success. However, if the locks are held for an extended period the error message may occur again. If you execute the sp_lock stored procedure, you can evaluate which process is holding locks on Object IDs 1, 2 and 3 of the dbid 2 (tempdb).
