[Twisted-Python] Imap client problem, help fro troubleshoot
Hello All, I have this[1] IMAP4 client in twisted, but I'am getting
this error too much, how can I troubleshoot it or how can I restart
the main loop after this failure?
Traceback (most recent call last):
Failure: twisted.internet.error.ConnectionDone: Connection was
closed cleanly.

Your code already appears to be based on ReconnectingClientFactory, so your client should reconnect after it loses its connection. The main thing that would prevent this is if you stop the reactor, which you also appear to be doing. If you want the reconnection attempt to succeed, then try not stopping the reactor. Jean-Paul

Hi Jean-Paul thank a lot for your reply, intentionally I'm not stopping the reactor this comes without my intervention
Failure: twisted.internet.error.ConnectionDone: Connection was closed cleanly
there is where I get lost, I'm using Solaris 10, python 2.6.2 and
twisted 10.1.0, could Solaris be the problem ?

There are several calls to `reactor.stop` in the example, though. The reactor won't stop unless that method is called.

I don't know why the connection is being closed. The most likely reason is that there's a problem with the protocol class which causes it either to raise an exception locally when handling data or which causes it to send something that the server dislikes enough that it closes the connection. You could rule out the former by enabling logging when the process starts, instead of only immediately before it stops. For the latter, you'll have to look at network captures and understand the behavior of the server you're talking to. Jean-Paul
OK Thanks a lot, I'll try that.
