Eh, we've been running Keep on the Shadowfell since late March in bi-weekly 8 hour sessions and averaging 2 encounters per session.. we tend to play slow and allow people to take their time.
We nearly TPK'd on the kobold hall. Two characters got away but all the tanks fell.
The large trap room on the second level of the keep was rather challenging for my party as well, mostly due to one of the characters getting stuck in the whirlpool trap early in the encounter.
That said, I find 4e to be just as lethal as any other edition is. Depends on how well you roll. I tend to average 4 criticals per session and with the way my group plays (tanks in front, party in the back) I have no problem blowing through the party's healing surges and general healing abilities.
Other than that other possible TPK experiences were due to my "figuring out" power levels and finding the right challenge for the party.
