Any friends out there who might know what this can be ?

Jul  1 23:47:18 www-ux saslauthd[595]: pam_mysql: MySQL err Can't connect to
local MySQL server through socket '/tmp/mysql.sock' (2)

local MySQL server through socket '/tmp/mysql.sock' (2)

My logs are full of these messages... I have to restart Sasl/Cyrus/MySQL
every second hour to
maintain it in business...

Any ideas ?

[Config]
(Redhat 7.3, Sasl: 2.1.5, Cyrus 2.1.5, MySQL version 3.23.51, build from
source with postfix as MTA)

This config has performed successfully now for over a year, until last night
it suddenly
started to fail... ???
