If you need a refresher, I recommend this good article. We know what deadlocks are and some of the common reasons they happen. Unfortunately, I don’t have the deadlock graph to show. The difference from what I understand in this StackExchange question is that the former is caused by intra-query parallelism. Notice that this is slightly different from a similar error belowĮrror 1205 : Transaction (Process ID) was deadlocked on resources with another process and has been chosen as the deadlock victim. Transaction (Process ID) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Recently, the job kept failing with the below error: As it runs, it maintains the fetch status/result of every operation in database tables which can be consulted if something were to go wrong. It is actually a PowerShell job that runs every night in parallel to collect the data from hundreds of instances (both SQL Server and Oracle). I have a nightly SQL Agent job that aggregates backup information from system views to power a Power BI dashboard that the DBA’s review periodically for database backup failures.
