OpenFOAM error-messages are often very clear. What do you think is wrong here? Hint: see your title. So, what can you do to fix it? Right, supply the right file. Did you run dsmcInitialise as the tutorials suggest?

Hi Bernhard,thanks for your suggestion,I found my flow field is too large, so, there are too many dsmcparticles,when I change numberdensities,it works fine ! this problem did not appear any more,why??
