If you look at our Intel64 Linux Coop lane, every single build is failing with 370+ test failures:


Here's one example run:


Many of the tests are related to program exit:

The error messages all seem different and none seem to be very helpful.

There is also a TAE being seen in a static constructor— i believe this may also be a program-exit related issue:
(We are seeing a similar problem on Windows32+64, and saw this failure EXACTLY once in the last week on Intel32 coop)

Probably unrelated to program exit: We are also seeing a LOT of failures, like in the hundreds, in GUI tests, none with helpful error messages. I do not know if this is related, I suggest we try to figure out what is wrong with exit/threads and then see if anything changes for the GUI tests. Every failure appears to be in the bucket (thread/program exit) or the bucket (GUI tests).

Here's the Windows TAE issue https://bugzilla.xamarin.com/show_bug.cgi?id=55984

What I described above as "GUI test" issues are actually a specific file IO issue and it's in System.Web, not GUI. I filed this separately as https://bugzilla.xamarin.com/show_bug.cgi?id=56000
