iPhone application crashes with Mprotect failed error (MonoTouch)

I have a problem with my iPhone application developed with MonoTouch.
I am developing an application that contacts a WCF Service, and when the WCF Service answer back, I update an UITableView with the returned data, when this is done it sends a new WCF async call, and when it answer back it updates the table again and so on.

The problem is that when it has done this in a variable amount of time, it crashes with an Mprotect failed error 12. This only happens when the application is running directly on the phone and not in the simulator.

I have tried to out comment where the update of the table happens, and making a Thread.Sleep(1000) before sending the next Async request to the WCF Service, but still the same error, but can run longer with out failing.

I contact the WCF Service through the "proxy" files, generated by SlSvcUtil.exe /noConfig http://mydomain/myservice.svc

My question is that can this error be avoid in a way or maybe with a workaround? Is it my fault, or is it a bug? It is actually because I shall use the application in my final school project, so it could be nice if I could fix it.

I post the console output, and a part from the crash report, but if you need more info please tell me, and I will post it. I am not a pro to use Mono or the MonoTouch environment it is my first time, so detailed responses would be nice.
