I have inherited a misbehaving system and am trying to troubleshoot it. The code
is not documented and I cannot produce a minimal working example that illustrates
the problem yet, as I don't know which parts are involved and how they relate.
The version of Twisted used is 16.1.1, running on Fedora 15.
My first attempt is to leverage Twisted's logging capabilities and retrieve
information about the place in the code that leads to the error:
from twisted.python import log as twisted_log
observer = twisted_log.PythonLoggingObserver(loggerName='twcore')
This produces the following entries in the log:
Unhandled error in Deferred:
CRITICAL _legacy twcore Unhandled error in Deferred:
Traceback (most recent call last):
