hi,all:
we met a problem that:
* Lost connection to MySQL server during query
SHOW TABLE STATUS WHERE ENGINE='MyISAM'
*sometimes it works
Since it is very unlikely that you lose connection on the socket file,
I guess you are using a PHP app, that uses the mysql driver and the problem
must be in the driver.
I would not look at mysql but at the PHP and PHP2MYSQL layer, mainly at the
later one.
Try different PHP (and driver) versions.
the application program and mysql server are in the same host
and i have add skip-name-resolv to the my.cnf and
extend the max_allowed_packet from 16M to 32M
our application connected to mysql server from mysql.sock
before the query which cause lost connection to MySQLserver..
we only ran some
In my experiences, there're three reasons below.
1. Your network is not stable.
2. Your mysqld's parameter called max_allowed_packet is adjusted too small,
trying to increase it.
3. Your mysqld's parameter called connect_timeout is adjusted too small,
trying to increase it.

I've never had a lot of luck tracking down this sort of problem. One
thing I've found to be a good first step is to add each server
involved to the other server's /etc/hosts file (and restart MySQL so
it notices).

Thanks for the reply. I'm not using persistend connections though. It

David,
Are you using persistent connections? Sounds like perhaps a persistent
connection is timing out.
Maybe a quick work around would be to call a check status routine (ie
- do a show status), just to see if the connection is still there. If
this fails, just do a mysql_connect... Before

Hi Vanessa,

You can just reconnect to MySQL if you get this error. :-) Trying to
