Something peculiar happened to mysql during a reboot and now vpopmail authdaemond is having trouble completing authentications....
/var/log/maillog says: Aug 24 08:36:15 hostname authdaemond: vmysql: sql error[3]: MySQL server has gone away This problem is spotty though. I have several successful authentications before this error occurs. I then have to restart mysqld before I can get any other authentications to succeed. I am still able to use the mysql client to connect to the server for an interactive session. What seems strange to me is that there are only two mysql daemons running: root 23923 0.0 0.1 5060 1108 pts/0 S 09:13 0:00 /bin/sh /usr/bin/safe_mysqld --defaults-file=/etc/my.cnf --pid-file=/var/run/mysqld/mysqld.pid mysql 23956 0.0 0.5 38620 5656 pts/0 Sl 09:13 0:00 /usr/libexec/mysqld --defaults-file=/etc/my.cnf --basedir=/var/lib --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-locking Every other instance of mysql 3.23.x I've ever run has about 10 child threads running, so this seems strange to see only one child thread. I have not updated any packages on this box recently. None at all, I swear. Suggestions to investigate? Googling on the "MySQL server has gone away" is a wild goose chase.
