I have mega set up to run backwards if too much monster exp is encountered.  I've noticed monsters sometimes tend to run in and out of the room when chasing.  It's not causing me any issues but I mentioned it to Gardner and he asked for a cap to be posted since it's not desired behaviour.

    This haunting, claustrophobic marsh is filled a clinging mist which leaves
the skin feeling cold and clammy. Strange cries echo, muffled, in the heavy
air, and shadows move just beyond the vision. The ground here degenerates into
a murky marsh, filled with spiky roots and floating clumps of moss. The water
reeks foully with an choking, acrid odour, but fortunately it is only
knee-deep. The occasional feeling of something brushing against you leaves you
feeling uneasy.

There is no "below" for them to stomp off to.  The room exits are N and U.

The 2nd issue, the one I wanted to look into, is the monster entered the room then immediately left the room and came right back in all in one round. 

2 adols chased them in, then (it seems) moved through an exit that does not exist, then re-entered the room from another direction.

Does majormud say "stomps out to below"?

I think it says "the down" but I'm not 100% sure on that.

[Ian]

shrug it just looks like it walked out and in.... is that really too many....?

I don't mind them moving around.  The problem is that it moved out in one direction, and came straight back in from the opposite direction (ie, not where it went).  Same with ms233's (lengthy) example.  It shouldn't leave to the ne and walk immediately back in from the sw.

Unless the message is printing the monsters movement direction, not its direction relative to me.  That seems probable.

Edit: Seems unlikely in this case, since there is no exit northeast:
Marble Passage
Also here: fire elemental.
Obvious exits: east, northwest, southwest
The room is dimly lit
The fire elemental flickers out to northeast.
A fire elemental flickers into from southwest.

Just go east kill the hydra, and move on.  I mean.... :P
