I'm running a simulation of a periodic DNA molecule. After some time I get,
sometimes the following error message:


A list of missing interactions:
         Proper Dih. of   3917 missing      1

Molecule type 'DNA_chain_A'
the first 10 missing interactions, except for exclusions:
         Proper Dih. atoms  414  417  418  421 global   414   417   418

Program:     gmx mdrun, version 2018.1-dev-20180306-33093601f
Source file: src/gromacs/domdec/domdec_topology.cpp (line 436)
MPI rank:    0 (out of 32)

Fatal error:
1 of the 10381 bonded interactions could not be calculated because some
involved moved further apart than the multi-body cut-off distance (0.5465
or the two-body cut-off distance (1.093 nm), see option -rdd, for pairs and
tabulated bonds also see option -ddcheck

How should I... proceed here? Is my system set up poorly, is it a bug in
mdrun? Suggestions appreciated.
