Hello, i would like to enable isochrone for long travel time (4 hours, 14400 seconds).  
I am using openrouteservice v7.1.0 through docker.  
I was thinking that the fastisochrones options were appropriate for that but, I’m having uses for starting server since I enable it for car profile :

```json
{
        "enabled": true,
        "maximum_range_distance": [
          {
            "profiles": "any",
            "value": 50000
          },
          {
            "profiles": "driving-car, driving-hgv",
            "value": 100000
          }
        ],
        "maximum_range_time": [
          {
            "profiles": "any",
            "value": 18000
          },
          {
            "profiles": "driving-car, driving-hgv",
            "value": 3600
          }
        ],
        "fastisochrones": {
          "maximum_range_distance": [
            {
              "profiles": "any",
              "value": 50000
            },
            {
              "profiles": "driving-car, driving-hgv",
              "value": 500000
            }
          ],
          "maximum_range_time": [
            {
              "profiles": "any",
              "value": 18000
            },
            {
              "profiles": "driving-car, driving-hgv",
              "value": 10800
            }
          ],
          "profiles": {
            "default_params": {
              "enabled": false,
              "threads": 12,
              "weightings": "recommended",
              "maxcellnodes": 5000
            },
            "car": {
              "enabled": true,
              "threads": 12,
              "weightings": "recommended, shortest",
              "maxcellnodes": 5000
            }
          }
        },
        "maximum_intervals": 10,
        "maximum_locations": 2,
        "allow_compute_area": true
      }

```

When the server starts, it begin rebuilding car graphs but after a moment i’am getting an error

```auto

```

It’s seems like it fail to generate `eccentricities_fastest_car_ors` file but can’t find why.  
Is there someone to help me ? I’ve tried to increase `maxcellnodes` but there was no effect. I think i miss something in the config but don’t know where.

Thanks in advance.  
Regards

We are currently investigating this issue. You might try whether this still happens on branch `releases/v7.2.x`.
