- database is restarted for whatever reason (log rotation, dba does an
upgrade etc etc).
- mysql has a 'wait_timeout' setting which could trigger it
http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#option_mysqld_wait_timeout
You need to do a
mysql_close();
mysql_connect(...)
before mysql_query works again - otherwise mysql_connect will just
return the same resource id (or I guess just use the 'new_connection'
flag for mysql_connect and skip the mysql_close()).
