Puzzling error with fresh install of 2.3.14

[patrick]

I've just installed Cyrus IMAP 2.3.14 on a fresh FreeBSD 7.2 machine,
and I'm getting some puzzling errors when I start up:

Jul  9 15:40:19 marzipan ctl_cyrusdb[11648]: archiving database file:

I've read some suggestions to change the DB format to skiplist for
everything (and I know this will get around this error), but I'd
really like to figure out what's actually wrong with my setup here. I
installed 2.3.13 on a FreeBSD 7.2 system a few months ago, and didn't
have any problems at all with the exact same settings.

Has anyone seen this before?

Thanks,

Patrick
