Jean-Louis,

Thank you for replying.

OK ... but I'm beginning to think there are network issues.
Last night this machine failed during the auth phase.  First
time that's happened.  'amcheck -c' later succeeded.

Would the amandad.*.debug REQ packet received be an entry like this?

  <<<<<
  SERVICE noop
  OPTIONS features=ffffffff9ffeffffffff00;

yes, but the one for the sendsize SERVICE

Increasing rep_tries?  I'm grasping for a solution, and
presuming that (from the context of REP in the *debug logs)
that REP indicates an attempt to reply to the server.
More tries = greater chance of success?  Evidently not.

Sorry, but I don't know which debug files you are talking about.
What's the error message you get in the email report?
