[Samba] Sick Samba 3.0.14a-3 Server - in a world of pain!

I wrote such a generic subject line because I'm stuck and not quite
sure where to go...

It's a Samba 3.0.14a-3 server running on Debian stable.  It uses LDAP
authentication and is the primary Domain server on the network.
Until around a month ago the server '''seemed''' to be fine, but now I
have to massage it to life every morning just so the users can access
it (killall -9 smbd, restart samba until most people can see it).
The clients are primarly WinXP SP2 machines with a few Win2K and one NT.

Here's the symptoms.
1) log.smbd was showing the following errors repeatedly " getpeername
failed. Error was Transport endpoint is not connected [2005/10/24
08:00:40, 0] lib/util_sock.c:get_peer_addr(1150)"
I thought this would solve the problem of
So after scanning through the mail archives I gleemed that it could be
a problem with port issues, so I added smb ports = 139 into the
smb.conf and viola the error message dissapeared.
However the 'hanging' samba server issue

2) The server hangs, in pieces.  It continually spawns smbd processes,
however for the clients that cannot connect to the server (forever
timing out) will never successfully connect to it until samba is
shutdown forcibly.  Even then it takes a few times before the system
is working again.

3) nmblookup hq (the server name) yeilds nothing.  Whilst Wins is
working on the clients and nmbd.log shows it is the Wins server,
nmblookup on the actual server doesn't work.  Not critical, but
wondering if it could be related.

4) I cannot find anything in the logs that looks wrong.  I possibly
need some more diagnostics to figure out the cause.

And last, here's a dump of the config file:
