Comment 1 Brendan Zagaeski (Xamarin Team, assistant) 2016-05-11 19:11:57 UTC
Some similar timeout issues have been reported by users to be fixed on Cycle 7 and higher. (See for example, Bug 38695, Comment 1, and the "preliminary customer verifications" in Bug 38695, Comment 5.)

I will mark as NEEDINFO to check if the reporting user on this bug still sees issues with Cycle 7 or higher. Thanks!
Comment 3 Brendan Zagaeski (Xamarin Team, assistant) 2016-10-07 16:48:26 UTC
Marking as "resolved noresponse" for now since there has been no further update from the user about the behavior after Cycle 7.  Cycle 8 – Service Release 0 contains additional changes to several timeout parameters that might also help with symptoms similar to this.

If the original reporting user still sees precisely the original symptom from Comment 0 when using the latest versions, please do reopen this bug report.


Thanks!
