Is it possibly exceeding the max_allowed_packet setting? –Marc B May 6 '12 at 22:49 provided info above –babonk May 6 '12 at 22:53 Ok, that's not it. Try pulling out individual queries from the file and running them yourself in the monitor. something in there's causing a crash/disconnected. –Marc B May 6 '12 at 22:55 The queries I randomly pull from the file work fine. I generated the SQL programmatically, and properly escaped everything. So I'm not sure what would cause an error if there is one. –babonk May 6 '12 at 23:11 1 I too have same problem ... –maaz Mar 25 '13 at 17:57 add a comment| 16 Answers 16 active oldest votes up vote 288 down vote accepted max_allowed_packet=64M Adding this line into my.cnf file solves my problem.

I added a 4th server for HaProxy to load balance and round robin so that we can have a little redundancy which is also working, except for 1 issue. I am logged into the MySQL client on the HaProxy server running the following query: show variables like 'server_id'; I am getting the results, but if I wait for a period of 5 or more seconds and run error 2006 hy000 the query again, i get the following error: ERROR 2006 (HY000): MySQL server has gone away No connection. Trying to reconnect... Connection id: 52 Current database: *** NONE *** Right after that i get the result with a different server_id which indicates that the load balancing is working. The problem that this is causing is that when i try to connect from my Spring/Java app, I can run queries for that short period of time and the connection drops. I figure if I can solve it on the HaProxy server, that would solve the other issues that I am having.

that had over 2 million rows. First time I tried moving that project from one computer to another I had the error "ERROR 2006 (HY000) at line ###: MySQL server has gone away" come out while restoring the backup. After a LOT of research on the internet my coworker and I found out that the problem had 2 origins: Some long queries exceded the max_allowed_packet size mysqldump was creating extremelly long insert sentences for that huge table Solving the firts issue is easy: just increase the max_allowed_packet value in my.cnf of the destination server: [mysqld] max_allowed_packet = 16M To solve the second issue we used the --skip-extended-insert option of mysqldump. The drawbacks of this option are that the dumps are much larger and that restoring those backups takes more time. You can see in this post of High Availability MySQL blog some benchmarks done with and without --skip-extended-insert and how a normal dump for 16M rows would take around 170 seconds whereas this workaround would take around 1,100 seconds. Almost 7 times more. Remember that --opt is used by default in mysqldump and it stands for: --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset That's the reason we use --skip-extended-insert to override the default --extended-insert behaviour that leads to a myslqdump command more or less like this one: $ mysqldump --add-drop-table --skip-extended-insert --skip-quick -u user_name -p database_name | gzip > database_name_`date +%Y%m%d_%H%M%S`.sql.gz Ref: http://dba.stackexchange.com/questions/5292/mysql-server-has-gone-away-obstructing-import-of-large-dumps http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html http://coding-journal.com/error-2006-hy000-at-line-mysql-server-has-gone-away/ Share this: Share Twitter Facebook Google LinkedIn Email MySQLERROR 2006, gone away, max_allowed_packet, mysqldump, skip-extended-insert You might also like Connect to MySQL over SSH with MySQL Workbench If you don't have phpMyAdmin installed on your server or you don't feel comfortable using it the
