I'm new to MonoTouch and 9 times out of 10, 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?
