I was getting the same error and it was being caused by my server running out of memory. I added a 1GB swap file and that fixed it. –Pikamander2 Sep 19 at 23:52 1 @Pikamander2 thanks for the hint! –ihsan Sep 26 at 9:10 add a comment| 13 Answers 13 active oldest votes up vote 4 down vote accepted It may be easier to check if the connection and re-establish it if needed. See PHP:mysqli_ping for info on that. share|improve this answer edited May 14 '15 at 14:46 cgaldiolo 525610 answered Oct 29 '11 at 23:15 Niet the Dark Absol 209k37240372 Good point, if you have a process that is intermittent then its better to release your connection so you don't used up all the connections. Rebuilding the connection is generally cheap. +1 –Yzmir Ramirez Nov 3 '11 at 0:48 add a comment| up vote 179 down vote I've encountered this a number of times and I've normally found the answer to be a very low default setting of max_allowed_packet. Raising it in /etc/my.cnf (under [mysqld]) to 8 or 16M usually fixes it. [mysqld] max_allowe

It's cheap, and comes with a private SSL cert. HOWEVER, their MySQL settings are such that any db connection goes stale fairly quickly, and then the hostgator staff try to convince you to use a VPS or dedicated server at multiple times the expense. I'm creating and deploying WebAPIs, which can have a 'conversation' which exceeds 60 seconds. When this occurs, the db connection handle is stale, causing any db operations after my timeout to fail. I'm in the process of implementing the following solution, but am curious if anyone else has solved this issue (where they can not modify their my.ini or my.cnf to give MySQL more resources) in a similar or completely different manner. last part of a hook_update: $ret = db_query( "UPDATE {my_table} set field1 = '%s', field2 = %d ...

Category: Troubleshooting ×Close Feedback sent successfully Thank you for your valuable feedback. We will use it to make piwik.org mysql error even better. The MySQL server has gone away (error 2006) has two main causes and solutions: Server timed out and closed the connection. To fix, check that "wait_timeout" mysql variable in your my.cnf configuration file is large enough. Server dropped an incorrect or too mysql error nr.2006 large packet. If mysqld gets a packet that is too large or incorrect, it assumes that something has gone wrong with the client and closes the connection. To fix, you can increase the maximal packet size limit "max_allowed_packet" in my.cnf file, eg. set max_allowed_packet = 128M, then sudo /etc/init.d/mysql restart.

has gone away" Part 1: max_allowed_packet. By peter_laursen. Last updated on August 10, 2009. 30 Most MySQL users have tried getting this rather cryptic error message: "MySQL server has gone away". The MySQL documentation describes lots of possible reasons for this here: http://dev.mysql.com/doc/refman/5.1/en/gone-away.html However this page is of little help for most users, I think. Dozens of reasons are listed, but except for the trivial ones (like physical connection was lost, the MySQL server or the machine where it runs has crashed etc.) there are a few reasons for this that are very common in our experience and a lot of those mentioned are not. Here we will discuss one situation that to our experience happens very frequently for people working across multiple servers. The situation is that if a client sends a SQL-statement longer than the server max_allowed_packet setting, the server will simply disconnect the client. Next query from the same client instance will find that the ‘MySQL server has gone away'. At least it is like that with recent server versions. 1) But the documentation at http://dev.mysql.com/doc/refman/5.1/en/error-messages-client.html .. also lists another client error: Error: 2020 (CR_NET_PACKET_TOO_LARGE) Message: Got packet bigger than ‘max_allowed_packet' bytes along with Error: 2006 (CR_SERVER_GONE_ERROR): Message: MySQL server has gone away. Actually I have not seen the ‘got packet bigger ..' error myself for many years. Not since MySQL 3.23 or 4.0. I am uncertain if a recent server will sometimes still return ‘got packet bigger' or not or if also this error message itself has ‘gone away'. If the ‘got packet bigger' message is still relevant with recent servers it would be nice to have it specified under what conditions it occurs and when only ‘gone away' will. If this error mesage is now ‘historical' it should at least be removed from documentation or it should be mentioned that the error no. is reserved for this message - but not used anymore. But it would of course be much preferable to have the ‘got packet bigger' error returned if that is the
