Description of problem:
After few days saslauthd processes allocates all memory (4GB) and casues server to swap. Restarting saslauthd solves the problem for another few days. I can see on memory monitoring that this is continuous so I assume there is some small memory leak but I do not know how to debug what is saslauthd doing. Daemon is functioning properly and log shows nothing interesting.
I am using saslauthd to authenticated to mysl via pam.
The only thing sasluthd logs is
Aug 8 10:10:30 rdesign saslauthd: do_auth : auth failure: [user=username.example.com] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error]
But I suggest that this is normal error due to password mistake. And there is max 20 of these messages per day.
Even shutting down the service looks normaly:
Aug 8 12:59:17 rdesign saslauthd: server_exit : master exited: 19122
Aug 8 12:59:17 rdesign saslauthd: detach_tty : master pid is: 23345
Unfortunately I could not try to reproduce it on other server as I do not have similar server.
