amandad: dgram_recv: timeout

Hey folks.

I've been trying to solve a problem with amanda for the past few
months.  Until yesterday it was only a problem on one (out of ~10
servers) client.  Now it's two!

Examples from the dump report:
  newww.gta. / lev 0 FAILED [Request to newww.gta.com timed out.]
  bento.gta. / lev 0 FAILED [Request to bento.gta.com timed out.]


bento has had the problem longer.  amcheck reports no errors with
bento.  today, amcheck DOES report errors with newww;
WARNING: newww.gta.com: selfcheck request timed out.  Host down?

Even though selfcheck...debug seems fine:
/tmp/amanda%# more selfcheck.20030102105821.debug 
selfcheck: debug 1 pid 61064 ruid 2 euid 2 start time Thu Jan  2 10:58:21

selfcheck: OK
selfcheck: checking disk /
selfcheck: device /
selfcheck: OK
selfcheck: pid 61064 finish time Thu Jan  2 10:58:21 2003

(ran it twice to be sure..same result, same report.)

The amandad..debug for this ends with:

amandad: It's not an ack
amandad: dgram_recv: timeout after 10 seconds
amandad: waiting for ack: timeout, retrying
amandad: dgram_recv: timeout after 10 seconds
amandad: waiting for ack: timeout, retrying
amandad: dgram_recv: timeout after 10 seconds
amandad: waiting for ack: timeout, giving up!
amandad: pid 61063 finish time Thu Jan  2 10:59:11 2003

The amandad..debug on the client when amdump runs is similar:

Help! I'm open to any and all suggestions.

FWIW, bento and the amanda server are on the same ethernet switch.  newww
and the amanda server are seperated by a firewall (which is, and has been,
correctly configured.  Two other servers on the same network as newww
still backup correctly.)

If you need any specific information from me, let me know and I can
provide it.  I'm not yet sure what will help you folks help me.:)

thanks.

...david
