the process dies halfway through with the following error: 2006, mysql server has gone away Ive heard about the MySQL setting, wait_timeout, but do I need to change that on the server at my office or the remote MySQL server? mysql mysql-error-2006 share|improve this question edited Jan 25 at 7:44 bpoiss 7,69311435 asked Oct 29 '11 at 22:44 floatleft 97752540 2 it depends of that witch server gives the error –bksi Oct 29 '11 at 23:01 1 possible duplicate of ERROR 2006 mysql server has gone away error (HY000): MySQL server has gone away –Simon East Oct 6 '14 at 0:40 For people getting here from Google: If changing the max_allowed_packet size or wait_timeout amount doesn't fix it, check your memory usage. 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_allowed_packet=16M Note: This can be set on your server as it's running. Use set global max_allowed_packet=104857600. This sets it to 100MB. share|improve this answer edited

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 mysql server has 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 ... WHERE vid - %d", $node->field1, $node->field2, ... $node->vid ); if (!$ret) { // get private storage directory for this node: $cexStorage = _cex_front_getCexStore(); $nodeFilesPath = DRUPALROOT.'/'.$cexStorage.'/'.$node->storeDir; $fname = $nodeFilesPath.'/recover.node'; $readyToWrite = serialize( $node ); file_put_contents( $fname, $readyToWrite ); if (file_exists( $fname )) { _dbgReport( 'seems to have worked!' ); } } Then this is called in my hook_form, right after I determine that node->nid is valid: function _cex_front_recover_node( &$node ) { if (!isset($node->storeDir)) { _dbgReport( '**************************** _cex_front_recover_node: no storeDir!!!' ); return; } // get private storage directory for this node: $cexStorage = _cex_front_getCexStore(); $nodeFilesPath = DRUPALROOT.'/'.$cexStorage.'/'.$node->storeDir; $fname = $nodeFilesPath.'/recover.node'; if (file_exists( $fname )) { $recovered = f
