Hello,

we are running a pretty busy mysql server and every now and then we get the following message from your php app. The app is connecting to a remote mysqld:

error: 2013: Lost connection to MySQL server at 'reading initial communication packet', system error: 54

Do you guys have an idea what may cause this?
