6 years ago Will look into this. I don't see the same thing on my setup. It is worrying since the crash log states "error: [Errno 10053] An established connection was aborted by the software in your host machine", so I suspect our "delay" method to avoid sending responses during HBT absent test case may not work reliably.

6 years ago Hi pawan25062. A few more questions to understand what is going on:
errno 10053 seems to be a timeout issue: the test harness has delayed several response messages until the end of the test, then tries to send them. It seems that the CBSD or OS has timed out the connection since it is a long delay...

6 years ago hi,
What os is this running on?
It is running on Windows
It is not clear to me: did this actually crash the server? Or, if you ignore the exception messages, does the test harness continue to operate properly? That is: is this fatal, or is it a nuisance problem on the display? If you go ahead and answer the question, does the test pass or fail?
We are able to choose answer even after all these errors and test case is also getting passed with these error.

6 years ago This appears to be an artifact of using delayed response to simulate loss of communications with the test harness. Device may send one or more requests while the test harness is not answering. Those requests are processed at the end of the test, causing response messages to be sent at that time. If the socket for the response is closed, these error messages are displayed.
Based on some research, this appears to be a nuisance message. Based on python forums, this is seen in Python 2.7, but not Python 3.
We could consider a different method to silence server, but may need significantly more time to generate a proper solution.
Hi,
Mock SAS giving error at the end of test case WINNF.FT.C.HBT.10:
