If the system is small enough, you can run it on a single core and the problem cannot occur. You could also try to use particle decomposition (-pd) instead of domain decomposition. Or use less domains, i.e. less cores in total or at least less PP nodes if you use PME/PP splitting. This will at least reduce the probability for the problem to occur.
