Hi all
My users are complaining that they get the odd disconnect while using my
site built with nevow/athena on FreeBSD 7.1 with the poll reactor. I
recently switched to twisted 8.2 release and am now observing 199
'Unhandled Error' out of 298436 logged requests with the following
traceback.
Any clues?
TIA, Werner
