Geert,

Sounds like you might want to get your network guys to double check the
network config settings between the client and the server - are your
local machine and switch/router ports all hard coded to the same media
settings (e.g. 100Mb/Full Duplex) and not reliant upon auto detect?
Depending upon platform, can you check with netmon or a `netstat -rn` or
similar for Unix.

>From my experiences (and I'm not a network guy in any way, shape or
form), when backing up large files using the BA client, I'd expect to
see many more of these TCP drop errors than when backing up many
thousands of smaller files. Also, I've found the TSM API client to be
much less tolerant of packet drops too (perhaps because we're normally
using it to back up large files again via a TDP).

Hope that gives you somewhere to start looking.

I keep getting the "session is lost" errors with a certain box.

I already changed the maxsessions, maxschedule, idletimeout, but no
changes. The errors keep coming.

Only specials about this box is the fact that it has large files (oracle
database) and that it is behind a firewall. I assume the big files (2
and 4 gb) are making the problem here.

Any hints where I can look next?

Thanks,

Geert
