Yeah, I'm leaning towards memory or maybe network right now.

I'm seeing some of these during client backups:
ANR0132E smnode.c(27085): Memory allocation failed: object sessP->qryBuf, size 
1048576. (SESSION: 5518)

This is on a win32 system so 2GB mem is max. I'll try reducing the
bufpool to give TSM some more of those gigs and doing some instrumentation for
tonights backups.
