1) How many Postfix master daemons are running on that machine?
If there is more than one, then the error may happen in the "other"
instance than the one whose configuration you are reporting.
2) Perhaps the LDAP lookup results return other results, occasionally?
You can debug (2) by looking at Postfix logging (qmgr, lmtp, etc.)
in the minutes after the postfix/virtual fatal error. If you're
lucky then there is only one delivery happening.
