A process that I am running against a SQL Server 2008 R2 DB throws the following message
[sqlits1]Transaction (Process ID 55) was deadlocked on communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
WE have two databases on the sqlits1 server (production and test) and the same message is thrown on both, implying that the problem is not with the individual databases but instead with the SQL Server instance itself.
The process that is throwing this message ran without issue a few months back and to my knowledge, no changes have been made to the server. Data has been added to both databases but no server changes of any kind that I'm aware of.
Any ideas what might cause this error? I'm not even sure how to begin to troubleshoot.
Thanks in advance for your help.
P.S. I am not a DBA nor a SQL Server expert. Just letting you know so that if I ask follow up questions for clarification, you will know why
