Ofer,

is your TCP/IP failure problem solved, if so I'd like to know how it was solved.

We're experiencing the same problem only not on MS SQL but on MS Exchange, the
error messages are different but I would guess the source of it all will be the
same.
What we can see is that that Exchange client is trying to send a verb as part of
its protocol but can't get it completed for some reason, the dsm error log will
show messages like the ones below,

21-08-2001 14:47:46 TcpFlush: Error 10054 sending data on Tcp/Ip socket 592.
21-08-2001 14:47:46 sessSendVerb: Error sending Verb, rc: -50
21-08-2001 14:47:46 TcpFlush: Error 10054 sending data on Tcp/Ip socket 592.
21-08-2001 14:47:46 TcpFlush: Error 10038 sending data on Tcp/Ip socket
4294967295.
21-08-2001 14:47:46 sessSendVerb: Error sending Verb, rc: -50
21-08-2001 14:47:46 cuConfirm: Received rc: -50 trying to send Confirm verb
21-08-2001 14:47:46 TcpFlush: Error 10038 sending data on Tcp/Ip socket
4294967295.
21-08-2001 14:47:46 sessSendVerb: Error sending Verb, rc: -50

on the server side a message is received like the following:

ANE4991I (Session: 20523, Node: PPNL10LEC01A_EXC)  TDP  MSExchg NT ACN3521
Exchange Application Client: FULL  backup of IS from server PPNL10LEC01A failed,
rc = 306.

(interesting enough the enclosed ACN3521 echange client error number is no where
to be found !)
you can also see that the session is in a state of receive wait and stays that
way until it is aborted due to the commtimeout setting (1200).


We're running Exchange 5.5 on NT4 SP6a using TSM API 4.1.1. and Exchange TDP
client V1.1.1.01.
The problem has been reported to Tivoli, I'm waiting for a reply, if anything
usefull comes by I'll pass it along.

regards Walter Ridderhof.
