Waiting for TSM server......

We are wondering, why the "Waiting" messges ?   What is it waiting for ?

The TSM server is 5.1.1 on AIX 4.3.  It is dedicated to TSM. I checked and
nothing was running at this time. No other sessions were active.

FWIW, these backups go DIRECTLY to 3590E1A FC SAN attached tapes.  The
client connection is a GIG-e card on a private internal subnet.

They are still running NT 4.0. I realize this is an issue when it comes to
the TCPIP settings/limitations of this platform.

Any performance options I can tweak on the server or client side?

Here are my current server options:
