Thanks Jeff, I too have Greg Kuhnert's dfix in place and it certainly 
helps but doesn't seem to prevent this particular problem.

I've modified the /usr/sausalito/swatch/am_pop.exp AM script for POP 
service to try restarting Dovecot twwice with a little longer wait between 
restarting and retrying the test login, as I found I had to sometimes 
manually restart it twice as well. We'll see...

I changed this:

 catch {exec /etc/rc.d/init.d/dovecot restart >&/dev/null}
 sleep 3
 # redo test, fail if get an error again

to this:

 # DT 2013-03-22 try to restart dovecot twice with longer wait between
 catch {exec /etc/rc.d/init.d/dovecot restart >&/dev/null} result
 sleep 4
  echo 'DT Trying Dovecot double restart...' >> /var/log/maillog
  catch {exec /etc/rc.d/init.d/dovecot restart >&/dev/null} result
  sleep 4
 # redo test, fail if get an error again


Just tested it now by manually stopping dovecot just before the AM event 
script, then let AM do its thing. Alas, Dovecot again did not restart, had 
to restart it manually :-(

Any other ideas?
