Tim -

The -50 return codes make me think of networking or pipe
communications failure, where the former would probably be a hardware
condition, and the latter could be OS congestion issues.  Your
initial posting contained elements suggesting that the system
involved is rather busy chasing ITM and Network Associates monitoring
tasks, which might be getting in the way.  You might check the TSM
server Activity Log, if not the Windows Event Log, to see if any
allied condition evidence there.
