to me this indicates that something happens in your structure which causes
the problem. Changing lambda gives you a slightly different trajectory and
the problem might then occur at a different point in the trajectory or not
at all.

When you make such tiny changes the potential energy landscape almost
doesn't change, but again the trajectory will be different after a few
hundred steps. Is it possible to write out the trajectory after each
mdstep for both processes at l=0.1 and 0.0999? Then you could compare what
happens in the first simulation right before it fails compared to the
second one which works ok.
