I tried a timestep of 0.005 but the result was the same.  Even 0.001 did
not help. 

Maybe I should mention that I also get a warning at the beginning which

step 0Warning: 1-4 interaction at distance larger than 1
These are ignored for the rest of the simulation
turn on -debug for more information

after which the simulation continues, but with NaN energies in the
output file
