My guess would be its a problem in the Cyrus code, specifically the 
rewritten quota code.  Do you have code that is creating a lot of users 
and setting a new quota on them?  I just fixed a bug specifically for 
this problem.

Did this problem start with 2.2.5 or with Solaris 9, or did you upgrade 
both at the same time?  Does 2.2.3 work on Solaris 9?
