XF 1.2 Lost connection to MySQL server

[Skarpy]

Zend_Db_Adapter_Mysqli_Exception: Lost connection to MySQL server at 'sending authentication information', system error: 32 - library/Zend/Db/Adapter/Mysqli.php:333

This error occurs 1-3 times a day. I can not understand why. Recently took a more powerful server, but the problem remained.

Unfortunately, this isn't something we can really do anything about at the XenForo level. This is indicating that the MySQL server seemed to close the connection unexpectedly (well, the connection was lost). The error is a broken pipe specifically (http://unix.stackexchange.com/questions/84813/what-makes-a-unix-process-die-with-broken-pipe).

It may be worth looking to see if there's a pattern as to when the error is happening. Is there a backup running and maybe the load on the server is actually high? It wouldn't be a totally surprising error in that case.
