[gmx-users] Dynamic Load Balancing Crash

I recently started experiencing a error with GROMACS 2016.3 during a
replica exchange simulation with 80 replicas, 480 cpus, and 40 GPUs:
Condition: comm->cycl_n[ddCyclStep] > 0
When we turned on DLB, we should have measured cycles
The simulation then crashes. I turned off DLB with the flag "-dlb no" and
the error did not resurface so I have to assume it really is the DLB
causing the issue.
Does anyone know what might be causing this?
