SQL Server Deadlock Problem - How to Resolve?

We have a SQL Job (2005) that from time to time will fail due a deadlock. The error is as follows:

Transaction (Process ID 52) was deadlocked on thread | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. [SQLSTATE 40001] (Error 1205). The step failed.

This is an overnight job which effectively loads a reporting database and performs various corrections to the data. There are no other DML statements running simultaneously. The error occurs about once a week on differing days and at different points in the data load process. So I am presuming it is not due to DML statements.

Turning on Trace Flag 1222 provides information that is next to useless (log records below). Most of the articles that I have read are related to transactions and queries and therefore locks related to data pages/tables but not many related to memory/threads/buffer resources.

I ran PerfMon with all counters that seemed relevant (Network related, Available threads, Available Work Items, Log Buffer Waits as well as the usual ones such as Processor & memory related) but there was nothing immediately obvious.

Could this job block itself? May be it runs asynchronous tasks and something is going wrong.

If not, that should be conflict with another process. Possibly you could set for your database single user mode before launch updates

Generally this kind of deadlock comes from a transaction using parallelism. SQL Server divides the query over several threads and then they deadlock on one another. An immediate fix is to add OPTION (MAXDOP 1) at the end of the query that is multithreaded. However, it's better to optimize the query and/or add appropriate indexes
