Just a shot in the dark, but is Postfix using
Berkeley DB for anything?

LMTP is shared among both applications and if
either needs to access the same DB then one or
the other will surely choke....
If master is dying then perhaps it is accessing
a DB from Postfix and Postfix is using an older
Berkely version?

Cyrus runs very well for a period of time and then just stops.  The last
message in the postfix logs is always to mutiple receipents.
