saslauthd eats memory

[Gyorgy Knyihar]

Hello,

I installed the cyrus-sasl rpm package on my Mandriva 2006.0.
The server is used by hundreds of users. I use pam authentication mechanism.
My problem is that saslauthd eats up the memory of the server. After a few weeks
run it ate 1GB of memory wich caused serious problems. After two days run top
shows the following:
