Linux sometimes kernel panics when starting memcached... (eek)

I haven't been able to duplicate this on 2.4.21 or 2.6test4, and I slam my
servers..

I'd say use the same kernel that LJ is using on their memcached servers --- 
they don't seem to have the KP problem.. :)

'course, I don't know what kernel they're running over there...  2.4.21
works great for me (2.6test4 seems to work, too, but that's pretty ambitious
for a production server).
