This is the mdrun output:
Initializing Domain Decomposition on 4096 nodes
Dynamic load balancing: auto
Will sort the charge groups at every domain (re)decomposition
Initial maximum inter charge-group distances:
two-body bonded interactions: 30.031 nm, LJ-14, atoms 40702 40705
multi-body bonded interactions: 30.031 nm, Angle, atoms 40701 40704
Minimum cell size due to bonded interactions: 33.035 nm
Maximum distance for 7 constraints, at 120 deg. angles, all-trans: 1.139 nm
Estimated maximum distance required for P-LINCS: 1.139 nm
Guess for relative PME load: 0.43
Will use 2400 particle-particle and 1696 PME only nodes
This is a guess, check the performance at the end of the log file
Using 1696 separate PME nodes
Scaling the initial minimum size with 1/0.8 (option -dds) = 1.25
Optimizing the DD grid for 2400 cells with a minimum initial size of
41.293 nm
The maximum allowed number of cells is: X 0 Y 0 Z 0

Fatal error:
There is no domain decomposition for 2400 nodes that is compatible with
the given box and a minimum cell size of 41.2932 nm
Change the number of nodes or mdrun option -rdd or -dds
Look in the log file for details on the domain decomposition

This is bizarre. Did you fix the periodicity of the original coordinate file
(conf_start.gro) and rebuild the system, or did you try to run trjconv on the
replicated system? The former is the correct approach.
