Hello,

every now and then I see this error on an otherwise perfectly working
Amanda system (server 2.4.4p3, client 2.5.1p1):

FAILURE AND STRANGE DUMP SUMMARY:
  host.staso / lev 0 FAILED [data timeout]


The client's sendbackup log for such a failed run:

On the server side, the amdump log contains:

[...]

Hmm, but most of the time I do _not_ see this problem.  Any hints what
could cause the problem or how to debug this further?  


Regards, Jukka
