[Dovecot] Dovecot, pam and OpenLDAP

Hello We have a Dovecot installation using only pop3 where auth data is stored in OpenLDAP and accessed using pam. With Fedora 2 everything has worked fine, but when we upgraded to Fedora 3 we started to get problems. After a while a lot of dovecot processes existed, and error messages was logged in maillog telling that the processes was too old. Then some error messages telling about memory leak was logged.

Our /etc/pam.d/dovecot looks like this: #%PAM-1.0 auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth

Any idea what is happening?
