Hi Wietse,
This is a syslog snapshot of the situation a few seconds earlier:
* postmap processes dying because of a missing file (remember, there is no
mention of the db file in the current configuration)
* other postmap processes creating/populating the db file "N" times, ergo
the duplicate entry messages
* some process creates the text file: it may do it once, or overwrite in
"N" times. Not sure which.
Every 5s: grep postfix /var/log/messages
