Warping around if it happens to you in all eq environments (all servers) could be caused by a known issue with everquest itself with hyperthreaded and duel core CPU's, especially AMD's... for more information on that go to the eqlive website and check out the known issues area...
For a fix for this in the eqemu environment, try this:

If you don't have a multi laired CPU then it's most likely a different problem, but if you do this is likely the problem
Hope that helps.
