That might have been my case.
We had almost all of the symptoms you described on 7.3.4. The case ran along
for months before we looked at the os. The answer turned out to be a bug in
the solaris 10 network stack which was introduced by a patch around last feb.
We patched the os up to recommended cluster for august08 and hey presto all
the probs went away.
We expected it to fix our problems with backups of some windows clients but it
also fixed the problem we had with savegroups hanging at the end, acsls silos
getting mixed up inventories and nmc losing track of sessions etc. Basically
any process that uses tcp sockets to talk to others was being impacted even if
they were on the same host.

I'm running solaris 10. Sorry about that.
My tech says he has another case, w/ almost identical issues, assigned
to him and they are also running solaris 10.
Thanks!

This discussion is interesting, but no one who said they are having
problems
has mentioned which OS they are using or anything else about their
NetWorker
configuration other then the version number. As a result, it is
impossible
to see if there are any commonalities to the problems that have been
discussed in this thread.
