error reporting @ top of page

This is driving me a little nuts... I recently had a mysql error start popping up, relating to CCK I think. It displays the error at the very top of all my pages. Until I can figure out the problem, I'd rather not have this warning constantly on display.

Under admin/settings/error-reporting I have it set to only write errors to the log -- yet it refuses to abide by this, and continue to print the warning on the screen. How can I prevent this from happening?

Thanks!

BTW this is the warning:
Warning: Got a packet bigger than 'max_allowed_packet' bytes query: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (1, 'php', 'Got a packet bigger than 'max_allowed_packet' bytes\nquery: UPDATE cache_views SET data = 'a:4:{s:6:\\"tables\\";a:132:{s:17:\\"nodefamily_parent\\";a:3:{s:4:\\"name\\";s:10:\\"nodefamily\\";s:4:\\"join\\";a:3:{s:4:\\"left\\";a:2:{s:5:\\"table\\";s:4:\\"node\\";s:5:\\"field\\";s:3:\\"nid\\";}s:5:\\"right\\";a:1:{s:5:\\"field\\";s:10:\\"parent_nid\\";}s:4:\\"type\\";s:5:\\"inner\\"; in...
