What version of Python are you running? Recent versions should have a
fix for this. Here's the makePickle method of SocketHandler:
def makePickle(self, record):
"""
Pickles the record in binary format with a length prefix, and
returns it ready for transmission across the socket.
"""
ei = record.exc_info
if ei:
dummy = self.format(record) # just to get traceback text
into record.exc_text
record.exc_info = None # to avoid Unpickleable error
s = cPickle.dumps(record.__dict__, 1)
if ei:
record.exc_info = ei # for next handler
slen = struct.pack(">L", len(s))
return slen + s
Notice the code to avoid the Unpickleable error.
