Well, watchdogs ARE about timeouts :)

I know nothing about ProPolice but would suggest removing for a test
and see if the problem goes away.

As for the debug_info and stats data you sent, there was nothing that
looked bad in it, but those are more of a dynamic tool, its when the
problem occurs that this will possibly show why.... I know, it doesnt
make it easy :(
