Lock request time out period exceeded.

Details
Product: SQL Server
Event ID: 1222
Source: MSSQLServer
Version: 9.00.1281.60
Symbolic Name: LK_TIMEOUT
Message: Lock request time out period exceeded.
   
Explanation

Another transaction held a lock on a required resource longer than this query could wait for it.

   
User Action

Perform the following tasks to alleviate the problem:

  1. Locate the transaction that is holding the lock on the required resource, if possible. Use sys.dm_os_waiting_tasks and sys.dm_tran_locks dynamic management views.

  2. If the transaction is still holding the lock, terminate that transaction if appropriate.

  3. Execute the query again.

If this error occurs frequently change the lock time-out period or modify the offending transactions so that they hold the lock for less time.
