have you minimized the structure first? can you do "normal
MD" on this one too, not the protonated and hydrated one?
try to only change 1 thing at a time or else it is hard to track
down the problem.

your heating phase will be very fast and that can cause lots
of problems, especially with a poor initial structure.
why not add a step to heat to 600K over some period
of time?
