I run my server on Red Hat AS4 Linux 4.x and back up 5 clients, one
of which is a Solaris 2.8.  After upgrading to 2.5.2 yesterday,
last night I got:

FAILURE AND STRANGE DUMP SUMMARY:

  episun7.med.utah.edu  c0t1d0s0   lev 1  FAILED [too many dumper retry: 
"[request failed: timeout waiting for ACK]"]

this repeated about 20 time.  The logs say:

dumper.20070503190001000.debug:dumper: time 3597.701:

Any ideas?
