Package: sasl2-bin
Version: 2.1.26.dfsg1-13
Severity: important
File: /usr/sbin/saslauthd
Dear Maintainer,
since upgrading to Jessie, all saslauthd processes segfault on a multiple daily
basis:

May 3 10:04:24 mail postfix/smtpd[17269]: warning: SASL authentication
failure: cannot connect to saslauthd server: Connection refused
I have not changed any configuration related to postfix, cyrus or saslauthd
during the upgrade. Prior to the upgrade, no issues have been experienced with
saslauthd ever.
