Grooves in trunk of palm tree

I think this is a king palm (not 100% sure). Here are some photos I just =
took today to show a possible problem.  Up until today I thought this =
was normal, but when I push on the tree, it sway very easily and I can =
see the trunk move at the ground.  Nothing appears wet or eaten by =
insects - everything I can see and touch is hard like a normal tree.

Anyway, anyone who can share some info about this tree - is this normal =
or not, etc - would be very much appreciated.

If you send me an email, please post to this newsgroup also as I do not =
check this account daily.
