First Sam I would open a case with support,
Second if the clients are SUNs then you can set the tcp_close I think
setting down some, it looks like the ports are not being released in a
timely manner.
Let me know what patch for the server and the clients for NBU you are
running. I have seen this before when you are using multiple streams,
and/or multiplexing.

Subject: RE: [Veritas-bu] Backup client connection timeouts??
bob,
it gets more bizare. i have rebooted several of the machines,
and the ones that have been rebooted are now working. oh well,
they ran for 104 days. it seems that only netbackup is effected
by this. all of the other services are fine.
i did look at the netstat for all the boxen and found a very
large amount of the following on the problem systems:
maindb01-0.bpcd bu01-0.1001 33580 0 33568 0 CLOSE_WAIT
maindb01-0.bpcd bu01-0.1005 33580 0 33568 0 CLOSE_WAIT
maindb01-0.bpcd bu01-0.991 33580 0 33568 0 CLOSE_WAIT
maindb01-0.bpcd bu01-0.1006 33580 0 33568 0 CLOSE_WAIT
maindb01-0.bpcd bu01-0.ufsd 33580 0 33568 0 CLOSE_WAIT
maindb01-0.bpcd bu01-0.1009 33580 0 33568 0 CLOSE_WAIT
maindb01-0.bpcd bu01-0.1011 33580 0 33568 0 CLOSE_WAIT
maindb01-0.bpcd bu01-0.1021 33580 0 33568 0 CLOSE_WAIT
please note that the webservers, mailservers and etc are having
the same problem. so it is not specific to the database.
i am going to take the database servers down tonite and see if
that fixes them. if so i guess its time to start looking for a patch.
