That's pretty weird that it's always the same 2-3 domain names.

You can verify the content of the relay_domains.db file at the time of failure
with a command like:

postmap -s hash:relay_domains and grep for those missing domain names

Another thing I think you could do see wheter it was a Postfix problem or
a database problem, is to temporarily switch over to using a btree database
instead of hash.
