Just a list of PAM modules should be sufficient, or perhaps the
configuration is you're using something less usual (such as a *sql module).

My belief is that this type of issue is due to a memory leak in the
specific PAM module, or due to the way saslauthd uses pam - it only uses
the auth and account facilities and not the session or password facilities,
which may prevent the module from performing it's memory cleanup.
