I am investigating the performance of a server running a third-party app. I was doing some ad-hoc monitoring when I noticed that 8 processes were waiting for the same object in tempdb. I used dbcc page to return the object id and object_name to return the object name which was ALLOCATION. My guess is that it would be something to do with memory but I can find no reference to ALLOCATION and have not come across it before. Has anyone else found similar errors?
