Hi TSM'rs

Being a Linux bigot, I managed to convince a new client to opt for a Linux TSM 
server over Windows. I am now starting to wish I had just gone for Windows. 
Unless you can help I might have to. Here's the problem.

Server Version 5.2.0.2 on Redhat 9
Client Version 5.1.6.2 on Redhat 7.3

The TSM server has no tape library or drive but is totally file based (400GB 
using software raid0)

Client backups are done via the crontab using 
"/opt/tivoli/tsm/client/ba/bin/dsmc incr"

The server just hangs during a client backup operation.....nothing in the 
activity report. Eventually the client times out but unfortunately the "dsmc 
incr" stays in the process queue. The next day, cron dutifully fires off 
another backup and so it goes. Eventually after a call from a frustrated 
customer, I have to start the server manually and run the backup manually. 
(Seriously not good!!)

Also, if a backup is running and you happen to do one too many "q act" 
requests, the server hangs.

By the way, only the TSM application hangs, not Linux itself.

Has anyone experience with Linux TSM server and seen similar problems?

Regards
Mark
