AFAIK $ git grep -in "lpib" Otherwith the limitation of or-tools is the limitation of the host machine RAM (node indices are encoded as int64). |

… yes lpib is not part of or-tools but that's the message I get from kernel.
Is 100 nodes too much for a 16 gb RAM system?

wrong data, node used more than once. SetRange() called with incompatible
values...
Most likely an error in your code.

… In that case, what could be the reason that it is giving solutions for 50
nodes but abruptly exits the program in case of 100 nodes?

What version of OR-Tools and what language are you using?
Version: ortools 9.6.2534
Language: Python
Linux
I'm using it to solve CVRP with 100 nodes. It crashes and dmesg gives following message:
Unstable LPIB (352800 >= 176400); disabling LPIB delay counting
What are the limitations of OR-tools?
