In September 1995 there was some talk on this list about an
OS/2 Warp user on a Gateway 2000 P5-90 experiencing timeouts
after ADSM backup had transferred in the area of 35-40KB of
data.  I am experiencing the same problem on the same hardware
system running OS/2 Warp version 3, ADSM client backup version
2.1.01 and using TCP/IP.  After establishing connection with the
server on MVS/ESA and entering my password, I can select the
backup incremental option from the GUI interface.  Backup
begins and about 40KB of data is transferred.  These small
files even show up in the ADSM inventory.  I have also been
able to archive and retrieve individual files.  However,
when trying to do an incremental backup, the OS/2 client gets:
ANS4017E Session rejected: TCP/IP connection failure.
The MVS server gets:
ANR0400I Session 1096 started for node TALAFOUS (OS/2).
ANR0481W Session 1096 for node TALAFOUS (OS/2) terminated - client did not
respond within 60 seconds.

I have tried things like altering TCPBUFFSIZE, TCPWINDOWSIZE and
SLOWINCREMENTAL.  All to no avail.  Does anyone have any ideas, please?

TIA,
