You'll have to be more specific than this.  What are the sizes of the
processes?  How many processes are running?  How much memory is on your
server to begin with?  What is your saslauthd setup?

Of course you're going to get lots of memory back if you restart cyrus..
it will kill off all the current sessions and just restart the number that
you've preforked.

As far as saslauthd, I need to know what backend you're using (we know of
one with some versions of heimdal for krb5 password verification... but
the problem is in heimdal not in saslauthd)

As it should if you're in a resource crunch.
