Something peculiar happened to mysql during a reboot and now vpopmail
authdaemond is having trouble completing authentications....
Aug 24 08:36:15 hostname authdaemond: vmysql: sql error: 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
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
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.
