You may first need to create it at /etc/my.cnf (this is only an issue if you're using the default install of mysql instead of a mamp stack or similar) contents of /etc/my.cnf that corrected this issue for me below: [mysqld] max_allowed_packet= 64M wait_timeout= 6000 share|improve this answer answered Aug 20 '12 at 22:08 Rafe Hatfield 45558 add a comment| up vote 2 down vote Try foll

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.

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 run

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 ...

I have been able to do this in the past (I was using MAMP), but now I get a ERROR 2006 (HY000) at line 7758: MySQL server has gone away everytime I try to import the dump. The database contains innodb tables. I tried copying the my-innodb-heavy-4G.cnf file to my my.cnf to see if those settings would help, but no luck. Any ideas on what to tweak?

Even the I/O Thread of MySQL Replication can be victimized by this. According to the MySQL Documentation You can also get these errors if you send a query to the server that is incorrect or too large. If mysqld receives a packet that is too large or out of order, it assumes that something has gone wrong with the client and closes the connection. If you need big queries (for example, if you are working with big BLOB columns), you can increase the query limit by setting the server's max_allowed_packet variable, which has a default value of 1MB. You may also need to increase the maximum packet size on the client end. More information on setting the packet size is given in Section C.5.2.10, “Packet too large”. An INSERT or REPLACE statement that inserts a great many rows can also cause these sorts of errors. Either one of these statements sends a single request to the server irrespective of the number of rows to be inserte
