   OSError: [WinError 10048] Only one usage of each socket address (protocol/network address/port) is normally permitted is unrelated to the this test being run. It happens on windows all the time.

   Shouldn’t it be getting worked around by this: https://github.com/bitcoin/bitcoin/blob/ce3b75690d10426e97d087ca600140a19bf180b7/.cirrus.yml#L192 ?

   I think that only lowers the probability, but it still happens

   Shouldn’t it be getting worked around by this: @sipsorcery any chance you can weigh in here? Can we improve this workaround in some way?

   @sipsorcery any chance you can weigh in here? Can we improve this workaround in some way?

   I have dealt with socket address in use problems on Windows in the past (the SIP prefix in sipsorcery refers to the communications signalling protocol). The problem I had was TCP sockets not closing DESPITE correctly calling the socket close/shutdown methods and even closing the owning process. Windows seems to ang on to the socket entry in some internal table and prevent the same, or a new, process from being able to reuse it for varying amounts of time (I recall it being up to 2 minutes but am probably wrong).

   The approach I used, and that is still used in my SIP library today is to set the SO_REUSEADDR on TCP sockets that rely on a well known port.

   I haven’t looked at the code for the test mentioned in this issue, and wouldn’t know how to set socket options in Python, but if it’s easy to do it may be worth setting that socket option. It could cause other problems, if multiple tests are actually attempting to use the same socket, but if that was the case it should result in the same error on other OS’s as well.

    Is this still an issue? Haven’t seen this in a while, I think.

    Closing for now.
