You hit the nail right on the head. I had 'freeze_tell = postmaster'
in the config so I would get report on messages that may get frozen.
Looking at those messages now, I do see it is happening when
relay_to_domains gets directly updated (every 15 minutes). I'll have
to change the method it gets created. Perhaps create a temp file and
raname it into place. Sometimes it does take 20-30 seconds to create.
