Transaction 641 deadlock sql server 2008 r212/29/2023 ![]() ![]() Take a full database backup (thus starting a new log backup chain) Start taking log backups. If you do this, enabling "read committed snapshot" may not be required. Switch to the SIMPLE recovery model (breaking the log backup chain and removing the requirement that the damaged portion of log must be backed up) (which you've done, yes) Switch to the FULL recovery model. When done testing, stop the SSMS query and run the cleanup code at the bottom. Run your process, and the deadlock should occur. In the place you want to simulate a deadlock, insert a call to spsimulatedeadlock. (Tested on 2008 R2 only.) You can leave it running as long as necessary. If the deadlock happened over a page of an index, set the "allow page locks" option of the indexes being Run the script below in a SQL Server Management Studio window.

You may want to enable the trace flag mentioned above, but if you are unable to analyse the data correctly due to a lack of knowledge of the SCOM internals, it may take a long time to troubleshoot This is caused by lock concurrency in your database instance.
