WordPress database error: [MySQL server has gone away]

I did not make any changes, and the host says that there is no problem with MySQL. Can anyone explain what the error means? and how to troubleshoot?

This is a shared hosting environment, and no recent changes where made to the site. Also other wordpress sites are encountering the issue with this same shared server.

This is not a WordPress error, it is from MySQL:

The most common reason for the MySQL server has gone away error is that the server timed out and closed the connection.

Talk with your host again.

Thanks, lousy host. I had never seen that error before though. –  Drai Oct 27 '12 at 16:06

Talk to your host and consider finding a new host; it's not that difficult to run a MySQL server.

Well, definitely DO NOT use Liquidweb as a host. I've been a *nix sysadmin for 20+ years and they are still fighting with me saying it is a script error. Really? 12 different plugins, a theme, Jetpack, WordPress core. All buggy to the point of failing regularly? Sad part is I know it is a MySQL config/server load problem and they keep saying "no errors in the main message log". Obviously they don't know how to monitor a MySQL server even after I sent them several URLs on the topic. Sadly I am now planning 2 days to move to a dedicated server far away from Liquidweb. So aggravating! –  Charleston Software Associates Feb 7 '13 at 4:49
    
Liquidweb is not a WordPress-recommended host. –  songdogtech Feb 7 '13 at 14:29
    
I know. I had been using them for years. I can't continue to recommend them at this point after several server crashes and now a mismanaged database. That said, there are some very good WordPress friendly hosts that are not on the WordPress-recommended list. However, after reviewing that link I may well go with one of the 3 that are on there now. Thanks for posting that URL. –  Charleston Software Associates Feb 8 '13 at 1:50
