Again, this morning:

mesg read: Connection timed out 

When it's not this message, it's data timeout error on the same DLE,
on the same host.

There are 3 other disks on this host, with not a signficant higher
amount of data, and they always backup OK.  This always occur on level
1 dumps it seems. Level 0 dumps always work just fine. I don't know
what to think.
