MYSQL服务器已经消失

Question

I am using WAMP server for my web application . Sometimes I see this General error: 2006 MySQL server has gone away'

I am updating the MySQL database through PDO PHP.

Any suggestions to avoid this ?

Answer 1

Try to debug the problem. This can be caused by any number of things. Commonly there are:

• The MySQL server crashed
• A comms problem between the client and server
• Abusing the client library in a way not intended, perhaps sending commands out of order or sending junk through the socket.

Last time I used it the PDO driver was quite flakey and it was possible to create the last case.

If the comms problem is likely in production, your application should reconnect and retry the transaction.
