Re: Lost connection to MySQL server during query
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. Claudio 2009/9/9 stutiredboy stutired...@gmail.com 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 sql that create table(s) i have read this article http://dev.mysql.com/doc/refman/5.1/en/gone-away.html and can get rid of the problems this article referred it seems that our problem is similar to this bug: http://lists.mysql.com/commits/9447 http://bugs.mysql.com/bug.php?id=15752 but, this bug has been fixed in 5.0.25 are there any suggestions ? or any other informaion (s) should i post here? thanks! stutiredboy Claudio Nanni wrote: Can you provide more details? network layout, type of client/app used, connectors,etc,etc?

Upgrading from 5.0.32 via a replication chain and bug 24432
Hi all, I've got a quite large database (23G) that is running on a 5.0.32 version of MySQL. I really want to upgrade out of 5.0.32 to the latest version of 5.1 (or even 5.4) but a straight mysql_upgrade of the database takes long enough that I'd have serious down-time issues (last time I benchmarked the upgrade it came in at over day). To try and work around this I wanted to set up binary replication from my current database (as master) to a new database. This has meant that I have run across bug #24432 (http://bugs.mysql.com/bug.php?id=24432) which means that replication is broken from my current version to versions above 5.0.34. The bug listing includes the following replication table: master (-inf, 5.0.23)[5.0.24, 5.0.34] [5.0.36,+inf) slave (-inf, 5.0.23)BUG#20188 both bugs, no error BUG#20188 [5.0.24, 5.0.34] this bug, no errorno bugthis bug, no error [5.0.36, +inf)no bugthis bug, error no bug which seems to indicate to me that there's no way out of the version I'm running aside from a mysql_upgrade. Does anyone have experience of this bug, or of any options I have that wouldn't require a significant outage ?

This may or may not be useful, but I've just upgraded from 5.0.51 to 5.1.36, which took about 6 hours using mysqldump+reload - the database is about 20Gb. /Per Jessen, Zürich -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
