Lost Connection To Mysql Server During Query
[15 Sep 2004 9:25] Joerg Klein Description: I have a two way replication on 2 servers. A<->B On each server I have the following entry in the server.err file every hour, if there is no activity(processing queries) on it alternatively if the position of the log event is the same as one hour before: ------------------------------------------------------------------------------- 040915 9:36:49 Error reading packet from server: Lost connection to MySQL server during query http://dba.stackexchange.com/questions/115716/error-error-reading-packet-from-server-lost-connection-to-mysql-server-during-q (server_errno=2013) 040915 9:36:49 Slave I/O thread: Failed reading log event, reconnecting to retry, log 'obelix-bin.006' position 79 040915 9:36:49 Slave: connected to master 'repl@10.10.10.32:3306',replication resumed in log 'obelix-bin.006' at position 79 040915 10:36:50 Error reading packet from server: Lost connection to MySQL server during query (server_errno=2013) 040915 10:36:50 Slave I/O thread: Failed reading log event, reconnecting to retry, log 'obelix-bin.006' position 79 040915 10:36:50 Slave: connected to master 'repl@10.10.10.32:3306',replication resumed https://bugs.mysql.com/bug.php?id=5588 in log 'obelix-bin.006' at position 79 ------------------------------------------------------------------------------- This Error has no impact on the Replication. It works without problems. How to repeat: - Suggested fix: - [6 Oct 2004 20:02] Matt Lord Hi, Thanks for your bug report! This is expected behavior. This reconnection is due to the slave_timeout value which is set to 3600 seconds by default (1 hour). This is in place because there are cases where the master may go down and come back up but the slave isn't notified so it stays in waiting on the same connection. This timeout will cause a reconnection so that a new and working connection will be made. Best Regards [11 Oct 2004 9:00] Joerg Klein OK, that's a good idea, but my eventlog and the *.err is full of these messages and it is more difficult to see if there is a 'real' error on the mysql server. [24 Jan 2005 15:29] Jesse Tutt I would like to be emailed with the solution to this problem when a response is sent. [8 Apr 2005 16:10] D Rickard I agree with Joerg Klein. It's a nuisance to have these entries in the error log when they are not "real" errors. As a newbie to MySQL

Just the last few days, I've noticed a few errors, such as: From a MySQL Slave: [ERROR] Error reading packet from server: Lost connection to MySQL server during query ( server_errno=2013) Or From Apache/Other: Lost connection to MySQL server at 'reading initial communication packet', system error: 110 At one point this evening, many webnodes reported this error for a three minute period (many such reports as this was in a busy period). However, the issues don't appear to correspond with any times of extreme load. For all intents and purposes, the connection/thread load on MySQL is at a normal rate (between about 10 and 40 connected threads), and Web load has been a LOT higher at times over the last few weeks. Could there bee other reasons for these connection errors, that I'm not seeing? mysql timeout slave share|improve this question asked Jun 6 '11 at 22:11 kwiksand 303615 sysctl -a, networking tuning, timeout settings, keepalives, buffer size.
