I'm new to MonoTouch and more times than not, when I try to run my MonoTouch app on the iPhone simulator (debug mode and regular), I receive a long error output that begins with the following message:
Error connecting stdout and stderr (127.0.0.1:10001) Couldn't register com.yourcompany.[appnamehere] with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.Stacktrace:
at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004> at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004> at MonoTouch.UIKit.UIApplication.Main (string[],string,string) <0x00089> at MonoTouch.UIKit.UIApplication.Main (string[]) <0x00014> at PodcastManager.Application.Main (string[]) <0x00010> at (wrapper runtime-invoke) .runtime_invoke_void_object (object,intptr,intptr,intptr) <0x00043>
And ends with:
=================================================================
Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application.
=================================================================
The weird thing is it will work some of the time. Once, a reboot of my machine did it. Others, just restarting MonoDevelop and/or the simulator.
I can provide the entire error output if you think that may help.
Any ideas?
-- Update -- after updating to 2.0.2 I have not seen this issue.
After playing with it long enough, and coming across this bug report I've come to the conclusion that until it's fixed the way to prevent this error is by NEVER stopping a debug session in the IDE. As long as you stop the debug session when the code is not at a breakpoint by hitting the home button it appears that you will avoid this situation.
