Hello everyone, i need increase max\_visited\_nodes more than integer max value. I got this error:

```auto
{"code":3,"error":"Unable to compute a distance/duration matrix: Search exceeds the limit of visited nodes."}

```

This is my config:

```yml
engine:
    profile_default:
      service:
        maximum_distance: 2147483647
        maximum_routes: 160000
        maximum_distance_dynamic_weights: 2147483647
        maximum_distance_avoid_areas: 2147483647
        maximum_waypoints: 2147483647
        maximum_snapping_radius: 1000
        maximum_distance_alternative_routes: 2147483647
        maximum_distance_round_trip_routes: 2147483647
        maximum_visited_nodes: 2147483647

```

When i increase the maximum\_visited\_nodes more than “2147483647” error throwed from java integer and long type converting.

Hey,

as you have already opened [an issue](https://github.com/GIScience/openrouteservice/issues/1979) for that, we’ll track any progress on this there.

Out of curiosity, this is getting close to the max. number of nodes in OSM - may I ask what you are doing/analyzing that the number has to be as high?

Best regards
