i started getting this too. after numerous reboots it still woudl randomly pop up. i finally just pulled battery, counted to 15, and it went away, for atleast now. i would think its some app. iv no idea
edit: an hour later in browser its still popping up on random pages. certain pages just freeze the browser then the error pops
ok, might have a solution, still testing. but it may have something to do w/ your google account and it syncing the "internet". go into accounts/sync then uncheck "sync internet" under your google account. we shall see...
