I know I have seen similar reportings of this type of error, but I have not
seen any comment on the reason for this type of error.

Example:               (during scheduled nightly backup window we receive)
     TcpFlush: Error 10054 sending data on Tcp/Ip socket 164.
     sessSendVerb: Error sending Verb, rc: -50
     TcpFlush: Error 10054 sending data on Tcp/Ip socket 164.
     sessSendVerb: Error sending Verb, rc: -50
     ANS1809E Session is lost;  initializing session reopen procedure
     ANS1809E Session is lost;  initializing session reopen procedure
     ANS1810E ADSM session has been reestablished.
          (then this section of error messages will continue for a second
socket number and so on until the
          backup has completed or the backup window has expired......)

This is happening on all our ADSM NT clients regardless of NT service pack
installed.  The ADSM clients are at 3.1.0.1.  Our ADSM server is MVS at
3.1.1.3.  Our network is an ATM backbone.

To date we have decreased our COMMTIMEOUT to 30 minutes and this has reduce
the number of clients failing because of timeout.

Any help to identify the cause of this situation would be most
appreciated......
