How to stop the spam: xmit: Serious Network Trouble

This treasure started showing up 30 times per second after upgrading from 1.4 to 1.6, making it impossible to administer the system.

I know it can be shut off, and is most likely an arbitrary setting.

Where could this be?

Documentation regarding the subject seems to be 404. It only popped up when I regenerated fresh config files for, the 1.4 files running a 1.6 client didn’t show the spam. On of the new files has the pooh setting.

That’s not spam in the normally understood sense and neither is it an error message that can safely be ignored.
