unable to open Berkeley

[Gary Smith]

Okay, I'm running pam_mysql/nss_mysql on this test box.  Both POP3 and IMAP are configured and seem to be working just fine.  They have been doing so for some time (12+ months).  While trouble shooting a script connection problem I found these entries in the log file.  Looking into production, I also have these same entries.  Indeed /etc/sasldb2 doesn't exist but it doesn't seem to impact login or user accounts. 

So, the question is why?  How do I fix this warning or make it go away?  It is happening roughly every 10 minutes.  I don't know if it's related to a connection of a user checking his/her email or something else.  On production there are about 10 connected users at any one given time on POP3 but the timing is still about every 10 minutes.
