How often does it break? If really a "complete system restart" is needed
to fix it, it doesn't sound like a Dovecot problem. Check if it's enough
to stop dovecot and then make sure there aren't any dovecot processes
lying around afterwards.

Kind of looks like auth process is hanging. You could see if stracing it
shows anything useful. Also are any errors logged about LDAP? Is LDAP
running on the same server?
