This is the primary database server and has nothing else running on it. 2 websites I have use it (both fairly high traffic). The mysql service went down the other day. I got no errors, it just wouldn't connect http://stackoverflow.com/questions/23371831/mysql-crashing-on-ubuntu-server-reading-authorization-packet until I restarted the service service mysql restart. Everything was fine after that until this morning at 5am. Mysql service went down again, this time with the error SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading authorization packet', system error: 0 So I restarted the service and it was fine again. I have read the docs and it says to increase the connect_timeout global variable to 10. It was already on 10 so I increased it to 30. Then 5 hours later it is down again with the same error as above. Anyone have any advice before I give up and use a PaaS? mysql ubuntu share|improve this question asked Apr 29 '14 at 17:52 Carl Markham 4,12821645 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote This old bug log reports many people experiencing the same error: Bug #28359 Intermitted lost connection at 'reading authorization packet' errors.

However I get frequent errors on connection; lost connection to I can usually eventually connect but after many retries. The error message I get is: Mysql.mysql(): Couldn't connect to SQL-server: Lost connection to MySQL server at 'reading authorization packet', system error: 2 I have read the information here: http://dev.mysql.com/doc/refman/5.0/en/error-lost-connection.html and also the comments to the bug http://bugs.mysql.com/bug.php?id=28359. There are quite a number of aborted connects as you can see: mysql> SHOW GLOBAL STATUS LIKE 'Aborted_connects'; +------------------+-------+ | Variable_name | Value | +------------------+-------+ | Aborted_connects | 2540 | +------------------+-------+ I increased the timeout from 5 to 15 sec: mysql> show variables like 'connect_timeout'; +-----------------+-------+ | Variable_name | Value | +-----------------+-------+ | connect_timeout | 15 | +-----------------+-------+ but this has not helped.
