Thanks for the pointer, this might be related to Windows. Also found a note on
the release docs for 7.4.5:
GTsc23458/23458nw_c: A Savegroup reaches its inactivity timeout but nsrmmd
still reads the session as active, causing processes to hang.
Have updated the servers to 7.4.5, am hoping I don't have to tune Windows.

This sounds like your NetWorker server's OS needs tuning. Not being a
Windows person, I can't offer any suggestions, but on Unix, this kind of
problem is eased by increasing various parameters such as the number of open
files, maximum number of processes that can run concurrently, etc. Try
looking on PowerLink for a Windows tuning document to see if anything turns
up.
