What version of DB are you running?  Does this happen immediately or 
only after it has been running a while?  On Solaris 9 with DB 4.1.24-25, 
we had a problem where DB functions would eventually return ENOSPC, 
which might be interpreted as "Virtual memory exhausted".  There has 
been a patch posted to Cyrus to fix this problem, but if you can't use a 
source package you might have to downgrade to DB 4.0.14 if this is your 
problem.
