This appears to be the same phenomenon I posted about last month (see 
http://www.gromacs.org/pipermail/gmx-users/2005-July/016181.html and 
and follow-ups). I've since had some off-list discussion with Berk Hess, 
but we are no closer to identifying a specific problem.

Perhaps this independent observation made by Chiloo suggests we are both 
observing something real whose cause needs investigation?
