saslauthd problem

[Derek Yarnell]

So I have a RHEL4 system that I am doing cyrus imapd on.  We are a  
kerberos5 shop and thus are using saslauthd as the auth proxy.  Now  
sporadically, saslauthd will error with the saslauthd internal error  
(worst error message ever) but then will succeed on the very next try.

Sep 14 17:02:22 cyrus saslauthd[24654]: auth_krb5: k5support_verify_tgt
Sep 14 17:02:22 cyrus saslauthd[24654]: do_auth         : auth  
failure: [user=pham] [service=imap] [realm=] [mech=kerberos5]  
[reason=saslauthd internal error]

Has anyone seen this behavior before? I am using all stock RHEL4, no  
funky stuff.
