Hi,
We here are experiencing a strange problem with our amanda backup system. It
is failing with the following message about half of the time. There seems to
be no pattern to the failures, ie: certain tapes or certain days of the
week. The dump summary seems to suggest a timeout, but we upped the dtimeout
value (also follows) based on a previous posting we saw that had a similar
error and suggested this was the solution.
Have tried re-installing, but still happens. Is there any other timeout
that could be causing this?
We are running Linux Red Hat 7, and the amanda version is 2.4.2p2.
Any help would be appreciated,
Thanks,
Davin
