Hi Mark,

This is a bummer to hear! This is starting to sound like a bug in the runtime. Could you submit a bug report to http://bugzilla.xamarin.com under MonoTouch with a sample test case that illustrates this problem? That will help tremendously in tracking down this issue. Let me know the bug # and I'll be sure to try and get the bring it to the attention of the appropriate developers.

Thanks!

Jeff

In debugging program crashes on

                    psFileType}, this.CreateDBOperationCompleted, userState);

Tried putting try/catch and it never hits the catch, doesn’t even give a crash log, program just ends.

Hi Mark,

You might be experiencing some of the WebRequest and/or async Socket bugs that have been fixed since MonoTouch 4.0.3. Does upgrading to 4.2.2 resolve these issues?

Hope that helps!

Got a weird issue with an iPad MT app. Web service calls when using AT&T provisioned iPad2 intermittently fails. Can get fail to reproduce over and over again. Same calls when turning on WIFI on device do not fail. Same calls on Verizon provisioned device never fail. Wireshark on server shows that request when failure never gets to the server.
It seems that after we get failure we can get through some recurring sequences of successes for a short time period then get a failure then another string of successes. Failures don't come after a set # of successes but it may be time based.
Monotouch version - mtouch 4.0.3.10366
Any clues or hints are welcome (other than Just use Verizon devices). We have app rolling out to an installation that has ATT standard.
