We experience this issue often @iweb on Macs and the only solution we have is to restart MySQL. It seems to be an issue with PDO and bound parameters which somehow causes a crash in MySQL, but so far we've not Identified the cause. Hopefully someone else can shed some light on this?

Hi,

Its a kind of error which happen there is issues with DB connections,  PHP script taking too long to execute or response is very large (which is probable in case of Magento)

==========

you can make the following changes to my.cnf settings:

max_allowed_packet = 16M
wait_timeout = 1800
connect_timeout = 120
Then need to restart your MySQL server.

===========

If the above solution doesnot work try to run your raw sql query and test if its actually working properly.
