Drupal watchdog database table flooded with same message over and over?

I've:

• Disabled cron
• Disabled database logging
• Cleared my caches
• Commented out the code that is being displayed as the error

And still, the same error message is being written to Watchdog.开发者_如何学运维 I execute: "delete from watchdog" and IMMEDIATELY after I check in the watchdog table, the same error is there.

Not that it would help, but here's the error:

So, my questions are:

1. Is there any way to see why this specific error is being triggerred over and over?
2. What could be "caching" this error?
3. ANY other ideas on what could be causing this?

Had to restart the server. MySQL was acting up.
