[Twisted-Python] [cpushare at cpushare.com: CPUShare Exception]

I wrote the below code in my server:

from twisted.python import log

# local
from cpushare.mail import send_exception

class cpushare_logging_observer_class(object):
	def __init__(self, factory):
		self.factory = factory
	def start(self):
		if self.factory.production:
	def stop(self):
		if self.factory.production:
	def emit(self, eventDict):
		edm = eventDict['message']
		if not edm:
			if eventDict['isError'] and eventDict.has_key('failure'):

to receive exceptions by email like the below if (send_exception sends me
an sms for the very first exception too). I do a very similar thing in
nevow, but in nevow I handle it through the nevow layer, not through

Now to me it seems that the below exception isn't really interesting to
me, any client could generate it by injecting garbage in the ssl

Does anybody has suggestions on the best way to filter out all
OpenSSL.SSL.Error exceptions before calling send_exception in the above
code? Thanks!

(twisted is great ;)
