Why is my Eris buzzing for no reason?

[McDoodle]

Randomly, at all times of day and night my Droid sets off two short buzzes in a row. I've used task killer, have charged it (thinking it was some 'low battery' warning), gone through my settings and can't find a thing to stop it! At first I was thinking is was letting me know of a new incoming text or email etc...only to find it's for NOTHING! It's bugging me...and at 3 and 4 am when it's waking me up it pissing me off! lol! HELP!

Am I totally missing something here?

It hasn't always done this...only started about three days ago!

You could try turning off Haptic Feedback. That would likely narrow it down to a notification for something rather than a rogue vibration from phantom touching.

When I was on 2.1, and I had something, you couldn't head a buzz unless you put your ear up to the speaker, only a problem in 2.1 not 1.5.
