BobZhome, your latest ROM is causing my phone to reboot, it is not all the time and it is not frequently, I will say once a day, I like your ROM by the way. Lately I having issues using my phone at work loosing the signal and yours fixed that. I moved to Harmonia which also is very stable at work. Just wanted you to know.
Of course I'll leave it to Bob to provide a definitive response to this.
But with something like this, the first thing I would try is disable any overclock for a day or two (or drop it to 480-600). If that solves it, you KNOW with great certainty that your current clock speed exceeds the phone's tolerance and to drop it a notch or two. (Of course if you're not OC'ed, just ignore this post).
Many people seem to believe that certain ROMs allow their phones to OC faster, because they don't reboot or otherwise visibly misbehave. Reality is the phone's OC tolerance is purely based on individual hardware, and no ROM can change that on a hardware level.
It is true that some ROMs may run the phone harder (and hotter) and thus trigger errors. The harder a CPU works, the more power it draws, the hotter it gets and the less stable it becomes. The same would be true with some apps. But mostly, it is complete coincidence whether an OC triggered CPU error causes one ROM to FC or reboot, while another ROM gets by without noticeable problems. The error was still there regardless on both ROMs (given the same clockspeed, temperature etc).
The exception is when the CPU shuts down to protect itself from frying, that is NOT a coincidence
At least this is how computers work, I assume these phones are the same.
I am not suggesting you shouldn't overclock (I OC both my phone and my computers). But whenever I install a new ROM, I disable overclock while I perform basic tests, until I see that it is stable. Otherwise I don't know if I am testing the ROM or my OC. Similarly, I disable OC when I perform backups and other data sensitive tasks -- say, downloading a flashable zip for which I don't have an MD5.
Once again, just disregard this if you aren't overclocked or already tried disabling it. I've been on this soapbox before, and the message wasn't very popular, so I'd better step down
