Last night was the second time my phone had committed suicide on me.  This time I was trying to set an alarm & was randomly unable to enter text.  I rebooted the phone and then started getting forceclose in google.apps & android.phone.  Great.  After getting ready to throw the phone through a window I found this:

Looks like there is about a 70 app limit on stuff downloaded from the market.  I removed a few apps, rebooted & everything seems OK now. Now I have no clue WHY this is, I am using App2SD with plenty of freespace left so this shouldnt be an issue, but it is.  Anyone else run into something similar?
