This leads me to a new suspicion: I had reboots nearly all the time when it was so hot in Germany in June/July. When it became so much cooler, I suddenly didn't experience any reboots anymore. Then I got several reboots again last Wednesday, and guess what, it was the hottest day since weks.
Above all, the sun was shining quite fiercely when I drove home, and it seems to me that my phone gets heated up much more if the sun is shining directly at it through the windshield and/or the open roof.
So, my current theory is that the problem with reboots (maybe not with the force closes some seem to experience, but I've seen none) is not really a bug in waze's code but the fact that waze is the one app that heats up my phone most.
If it's quite hot in the car, the phone might overheat and either be rebooted by some security function in Android (though other means like the iPhone's "Please wait for the phone to cool down" would make more sense here) or be forced to reboot by some flipped-over bits in kernel memory or random outcomes of CPU calculations. If some bits run havoc within waze's memory, this might even explain force closes.
I guess it's more likely flipped bits than a security function as I sometimes had no reboots although the phone got so hot I could barely touch it while on other days it was only "rather hot" but there were reboots.
Still, I never experienced a reboot on those cloudy days when the car was not heated up when I drove home, nor did I ever get one when I drove to work in the morning, so I do suspect that heat is at least one of the problems here. My car being quite dark und thus very hot on sunny days might add to the problem.
Any similar experiences?
well, i do charge my phone while driving, but my motorola milestone with 2.1 was at least 10c hotter than my nexus, all the time, and it worked much better on waze.
Then again, it WINTER here in Argentina, and i think its the coldest winter i can remember, so, no, no hot days, many nexus one with 2.2 reboots.
Also, i tried running google navigation for the same travel distances that rebooted waze many times, with no issues.
