Mysql keeps hanging, it gets in a loop of errors with socket operation on a non-socket but the only socket I know of is the one to connect and it is still a socket.

     I am researching and trying to understand what is happening to correct it.  If you get cannot connect to the database when you go to our website or anything using MySQL here, that is why.

     This is unrelated to the upgrade.  It started happening several days before.  I had hoped the upgrade would resolve it.  The machine in question is quite generously equipped with memory (16GB), so not a memory issue.
