Hi,

You set category to "MySQL Websites: bugs.mysql.com" so I am not sure if you are asking question about your setup or issue with bugs.mysql.com website. Our website is running fine so I assume you just set a wrong category.

If you are asking about your system please
 - write details about your system
 - upload your mysqld log file and config files
 - explain what actually happened, how did your server "gone away"

The error you seen "MySQL server has gone away" shows that your client lost connection to your mysql server. This can happen due to different reasons
 - your client network connection was broken/reset/changed/interrupted...
 - your servers network connection was broken/reset/changed/interrupted...
 - your server disconnected your client for some reason (too long connection for e.g.)
 - your server crashed (and auto rebooted as the error "self solved")
 - something else

Without logs we cannot guess what it is and only if this was because your server crashed this is a bug, in all other cases it would be normal behavior.

Hi Mr. Chabot,

This is a forum for the bugs with repeatable test cases.

A test case must be complete, so that we can be able to repeat it. A test case should consist of the set of SQL statements that always lead to the above SQLSTATE.

Since you have not supplied us with a test for the entire two weeks, we are setting this bug to the status of "Can't repeat".
