Salutations, all. Xamarin Release Engineering here with this week’s edition of the Mono Weather Report.

 

Here are the top failures currently making Jenkins builds unstable:

 

1. MonoTests.EvaluatorTest.TypesTest.EnumType [New]

 

Occurred 60 times across each lane/architecture.

2. MonoTests.System.Net.Sockets.SocketTest.SendAsyncFile [Existing]

                                                                                    

Filed as https://bugzilla.xamarin.com/show_bug.cgi?id=43172 , currently unassigned.

 

This has been failing for a very long time. It used to only occurs on Linux but on Linux it fails over 20% of the time. (It has also been seen on Android.) It is possible this is only an issue in CI (see akoeplinger note in bug). 

 

The failure is consistent and looks like:

 

                                                MESSAGE:

                                                System.Exception : Could not abort registered blocking threads before closing socket.
