[Wayne Luke]

These mean that MySQL is closing the connection to your PHP app before returning a result. Most often this is caused by two reasons...

1) The wait_timeout (and corresponding innodb_lock_wait_timeout) are set to less than 120 seconds.
2) The max_allowed_packet is less than 4 Megabytes. 8 Megabytes is recommended here.

This can also manifest because PHP doesn't have enough memory to actually process the query. It is recommend that you have PHP configured to use up to 128 Megabytes. Larger sites (millions of posts) may need more memory.

You will need to consult with your hosting provider on how you can change these values. If this is an unmanaged server and you do not know how to make these changes, you will need to search the web for answers. Usually searching on the OS Name, Version and keywords like MySQL Configuration or PHP Configuration helps me find what I need.
