dovecot - Jan 2012 - failed: Too many levels of symbolic links

All,
My dovecot install works great except for one error I keep seeing this 
in my logs.  The folder has 7138 messages in it.  I am informed the user 
they needed to reduce the number of messages in the folder and believe 
this will fix the problem.  My question is about where the problem 
lies.  Is the problem related to an internal limit with Dovecot v2.0.15 
or with my Debian (3.1.0-1-amd64)?

Thanks

You have a symlink loop. Either a symlink that points to itself or one of the
parent directories.
