LXC: MySQL connection problems inside container

[gkovacs]

We have migrated several LAMP containers to LXC, and experiencing repeated MySQL connection problems since then. The problems only happen inside the containers: Apache / PHP sometimes can't connect to the MySQL running on localhost. There were numerous occasions where MySQL has "gone away" during a mysqlcheck session.

Anyone else experience similar issues? Any idea what could go wrong? Nothing in the logfiles...

I'm experiencing issues with PVE 4.1, AppArmor, LXC migrated from OpenVZ and various services that use UNIX sockets for communication, like mysql. Have you tried setting lxc.aa_profile like described here?
