Sorry Amiel, no solid solution for me yet either.

Hello Bill,

Did you find a solution to this? I'm afraid I am also being killed by this.

Could it be a timeout problem and MySQL is closing the connection? There is a MySQL option "autoReconnect" but I don't feel comfortable with it.

Thanks,
Amiel

Sorry for the repost, this exception is now randomly showing up, still causing problems eventually. What should I look for as possible causes to this?

any ideas on what system or configuration option could be causing this? I don't see it on the much busier production server, but after a while, this appears to be killing the app. And then pingdom and insanity begin to kick in...

Thanks.
