Thanks. I removed all of the "home" apps as suggested by another
responder (I didn't remove the homeip app because I find it very
useful.) That was early yesterday and the N810 has not reset itself
since then nor have I gotten the "intensive cpu usage" message.

The N810 is only about 6 weeks old. The battery seems to drain awfully
quickly, and more quickly since I had the misbehaving apps causing
intense cpu usage and frequent resets (I believe the intense cpu usage
caused the resets). I'm wondering if this has drastically shortened the
life of the battery.
