Mark,

could you please audit & test this?

https://github.com/markwj/Open-Vehicle-Monitoring-System/commit/ad17c2662942536bc391cee282debbfcdd2ae2f5

I've reworked most of the complex sprintf() calls in the net and net_msg modules now. I also added a simple crash debug & checkpoint utility to be able to measure the effect and possibly narrow down remaining occurrences. It seems I've gained a lot of stability, had only two watchdog timeouts during the last week, no stack problems at all.

I hesitate to merge into the master because I currently have link / connectivity problems, especially during driving. I introduced a GPS logging to optimize my antenna positions and managed to get some really nice tracks three days ago, so I don't think this is related to my changes... but I'm not 100% sure. I tried different antenna positions and another GSM network, but the connection keeps dropping when moving the car, and GPS position updates need minutes. Could be weather conditions ...or some tricky race condition bug?

Thanks,
Michael
