Waiting for ack

[James Stevens]

I am having difficulties in running amanda. I am unable to get a backup (but
once was) and I think it was after updating some RPM on my system. It takes
30 minutes to fail and the only info I can find in in the amandad.debug file
on the client. I get 4 lines of
  amandad: waiting for ack: Connection refused, retrying
followed by one line of
  amandad: waiting for ack: Connection refused, giving up!
Any hints as to what went wrong?
