Srv event 2021 running wild

[Guest Rich]

I have a file and print server that has become inundated with the following

Srv warnings, event 2021, with the # being filled in with a variety of

different numbers. How do I get to the bottom of this? every article i've

come up with says it could really be anything causing this with not much help.

 

The server was unable to allocate a work item # times in the last 60 seconds.
