"status":207 ("status_message": "Cannot find route between points")

[ArGeBre]

Hi,
I compiled a very recent version of OSRM (July 23rd) and ran it with an even more recent Geofabrik download of Germany. Everything works fine (build from source, osrm-extract, osrm-prepare, osrm-routed with nearest and locate queries. However all viaroute queries result in status 207 no matter which points I try - even a route between identical points, which I believe should result in a status 0.
My system is a Debian "wheezy" 64 bit:
Linux osrm 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux
Any ideas?
Arne

All looks OK...

Hi again,
in order to double-check I downloaded a subset of the German map (Niedersachsen) and tried again and guess what - it worked! Then I re-build the map of Germany and got the same error (message status 207)

My test case:
/nearest?loc=53.0853143,8.8319732 (works with boths maps)
/nearest?loc=53.1452964,8.1786671 (works with boths maps)
/viaroute?loc=53.08531,8.83197&loc=53.14529,8.17866&instructions=true (works only with Niedersachsen)

Any help appreciated...
Arne

Are you running on real hardware or a VM?

[ArGeBre]

On real hardware - host to a number of VMs but not under load (load
average: 0,11, 0,16, 0,17) with 16 GB RAM...

I just re-compiled in DEBUG mode and when starting osrm-routed I get end
endless stream of error messages with the German map:

Not so with the Niedersachsen map

[DennisOSRM]

This makes sense, it basicaly says that your data file is broken. It looks like the free space under /tmp was full when the file was preprocessed.

[emiltin]

it would be good if osrm would output a meaningful error message if it runs out of disk space, and delete any half-baked output files?

[ArGeBre]

Agreed!
And it would be helpful to be able to specify an alternative location
for temp files. My /tmp partition is 1GB an 100% full when running the
osrm-prepare command. The temp filename is dynamic so I cannot even use
a soft link to point someplace else...

[DennisOSRM]

@ArGeBre good point. Will implement a more safer way to store temporary data.

[ArGeBre]

Wonderful! My test runs had come to a halt because of that. Looking
forward to a new version...

[ArGeBre]

Hi, any progress on this issue? Just downloaded fresh git clone and was planning to give it another try...

[DennisOSRM]

OTOH, i think this was implemented like 3 months ago with this guy:
https://github.com/DennisOSRM/Project-OSRM/blob/master/Contractor/TemporaryStorage.h#L81

[DennisOSRM]

Found it, it's done with #801

[MarioMobile]

hi
I get the error on some routes on my old and on my new server - so now I tried the demo-Server
http://router.project-osrm.org/viaroute?loc=47.2811722,11.5278353803541&loc=47.1581976694319,11.7305527936659&output=json&alt=false
also returns 'Cannot find route between points', status 207
regards

[Smarre]

I can confirm same as @MarioMobile, with http://router.project-osrm.org/viaroute?loc=60.25486045,24.8686498668678&loc=60.26287425,24.8527709929466

Funnily, the routing works with the web frontend, guess I’ll dig into how that does it.

[Smarre]

Okay, it seems thatthe web ui fails too, but it behaves differently. Note, that this is git version, I’m using.

[DennisOSRM]

There's plenty of unconnected roads in that area, @Smarre. All the purple spots are badly connected and it is not possible to go from one unconnected piece to another.

[Smarre]

Okay, it’s strange, since Google Maps gives does give me a route. Also, this kind of routing used to work in past; I think with git build like 1 year ago or so.

[DennisOSRM]

As mentioned above, it is a data issue with all the unconnected roads lying around.

[ArGeBre]

Hi guys,

my original post referred to an "Cannot find route between points"
message caused by a silent error that occurred while building the
network (/tmp partition too small).

Maybe move this topic to a new thread?

Cheers,
Arne

@ArGeBre: that’s okay for me, but I won’t do anything, if @DennisOSRM thinks there is nothing to fix. Myself, I don’t really understand why the routing should fail, there’s road close enough to the point; there is a house which Nominatim converted the address to coordinates, to the coordinates here.
