Client gets stuck

Hi All

Below is a part of my LOGfiles - The situation is as follows: 
 
 - Client NetWare 6.0 SP3
 - TSM Client Version 5, Release 2, Level 2.3
 - TSM Server Version 5, Release 2, Level 2.5
 - TSA Backup Module: TSAFS.NLM
 - Environment: 2 Mbit WAN-link

Sometimes... unfortunaly not everyday - we see a problem with a NetWare server 
(and sometimes a NT server with Oracle too) freezes...  as seen in the logfiles 
we see that suddenly the connection is abrupted in some way... the funny thing 
- or sad... - is that while this session hangs we have other nodes sending data 
on the same WAN-Link - as seen in the DSMSCHED.LOG this server hangs until the 
session is closed on the client (by the way CTRL+C isn't possible - the only 
way to close is to "kill" the session with "UNLOAD DSMC" with an overwhelming 
risk for a multiple ABEND). Any ideas??

Best Regards
Flemming
