Ok Guys, thanks..

I know about the database going away and various things can cause it such as resource overload, time out, etc..

In this case though the errors I get are always basically the same:

Invalid SQL:

SELECT *
FROM style
WHERE (styleid = 39 AND userselect = 1)
OR styleid = 39
ORDER BY styleid ASC
LIMIT 1;

I believe there is something causing the issue that is making the database server go away related to this query. In other words, I do not believe it is the database going away that is causing this error. Hope this makes sense. lol

It only happens a couple times a day usually and I have tried to rearrange some cron tasks, back ups to make sure it is not a resource situation. It could be but I am not seeing any indication.

No, this is not related to the redis issue I was posting about before. I have stopped using dbtech optimizer and am no longer using redis.
