Ok just to take the possiblity of it being my system I was testing on
out of the equation I had a fairly pristine debian 3.1 dev server that
was doing nothing so I installed it there and am having the same issues.
Again from the standard debian packages with the gmysql backend.

To be clear though the logs below are from my unstable system.
Here is the logging I currently get

**** make the query here ***
* note the first response came back in error according to host see belowbut it did not cause a crash
* the second time it had to dip the db however was a different story
* so the logs that follow came after 1 query, then let the query/packet cache timeout,

I also pasted the query that was printed in the logs  directly into the cli and this was the response.....

1 row in set (0.00 sec)

as far as I can tell that looks valid to me.

Is the next step to compile my own with debugging ? What would be the best way to track this down ?

I willing to do anything I can to help.
