Acho que sua pergunta é "o que posso fazer para corrigir isso?"
Fazendo essa suposição:
Perform the following tasks to alleviate the problem:
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.
If the transaction is still holding the lock, terminate that transaction if appropriate.
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.
E se isso não funcionar:
In this scenario following changes must be done in the offending transaction: 1) Modify the Transaction use query hints (use RECOMPILE,MAXDOPhints) 2) Run big Transaction in smaller transactions. 3) Upgrade Hardware if possible.
