As the subject tells... When NetWorker backup a save set, it loads Save.NLM,
one for each save set. When done with the save set, Save. NLM should unload
but it isn't always working. So after a few weeks of running the server
collects around 8 loaded Save.NLM and then hangs. The Save.NLMs that's left is
un-unloadable so it's not possible to "clean" the server.

NW 6.5 SP6
Legato NetWorker 7.2

Anyone who have experienced this problem? Or have an idea where to look for
the solution?
