Comment by Jan de Groot (JGC) - Thursday, 04 June 2015, 08:01 GMT These messages are logged at debug level, you can change syslog config to filter out debug messages. I will not remove this from Cyrus SASL, as debug logging is the only way to debug issues with SASL when not running interactive, for example when running a mailserver. ** Bug watch added: Debian Bug tracker #805310 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=805310 ** Also affects: cyrus-sasl2 via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=805310 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cyrus-sasl2 in Ubuntu. https://bugs.launchpad.net/bugs/827151 Title: Annoying log message "DIGEST-MD5 common mech free" Status in Cyrus-sasl2: Unknown Status in cyrus-sasl2 package in Ubuntu: Confirmed Status in cyrus-sasl2 package in Debian: Fix Released Bug description: I recently updated the libsasl2-modules to 2.1.24~rc1.dfsg1+cvs2011-05-23-4ubuntu1 in oneiric.
