MySQL server has gone away reading from vb3_style

[Martin_S]

Hi,

after updating to vbulletin 4 I get the following error mail some times per week:

Invalid SQL:

SELECT *
FROM vb3_style
WHERE (styleid = 4 AND userselect = 1)
OR styleid = 4
ORDER BY styleid ASC
LIMIT 1;

MySQL-Fehler : MySQL server has gone away
Fehler-Nr. : 2006

I know that "MySQL server has gone away" indicates a timeout. But hey, the statement is one of the easiest ones. And I don't get the same error with other statements!
What's wrong with this statement or the table? The Table only contains two records: the default style and my own style (with styleid 4)...

Thanks for help!

Martin
