Try repeating it with constant volume - i.e. NVE. I don't think you can
expect a constant pressure simulation to necessarily conserve energy,
although I could be wrong. Once you have equilibrated a suitable pressure
you should probably switch back to constant volume anyway. The same types of
arguments apply to the type of barostat as to the thermostat.
All the best
