Hello Guys,

I would like to use PTV xRouteServer with feature layer (with TruckAttributes) on linux but unfortunatelly I have some issues. When "featurelayer" folder is presented under the map folder (EuroPremium.geo) xRoute server could not be started. If I remove the "featurelayer" folder the server can be started but obviously feature layer could not be used in route planning.

Here are my environment's parameters:

xRouteServer version: 1.24.0.0 x64 gcc4
JVM: Java SE Runtime Environment1.8.0_121-b13 (amd64)
OS: Ubuntu Server 16.04 LTS
Map: PTV_Europe_City_Map_Premium_2017_1H_8

Here are the xRoute error logs when "featurelayer" folder is presented:

Could you please help use to figure out why we get the above errors?

Thank you in advance

Hi guys,

as mentioned via email: in case of a blocking issue you should always get in touch with support.
So let's raise a ticket!

Best regards Bernd

Here we go. Looks like we have found the cause for the trouble:

the customer uses our default deployment generated from the data setup. The deployment contains all featurelayers without trafficincidents. Docker has a default shared memory size of 64Mb. In our test deployment the /dev/shm folder has 220Mb after starting the xRoute.
We think the shared memory should not increase after the server startup, at least regarding the FeatureLayer side. We are doing some tests, but 100 Mb should be sufficient for the TomTom 2017 Europe map, for all the FL.
Of course, the more FL themes you use, the higher shared-memory size you'll need.
We think a recommendation of 256mb of shared memory should make a docker production system safe. The memory is only required on startup and no additional memory is required per request.
So please check the option "--shm-size=256MB" of "docker run" (produces a shared-memory segment of 256MB in size)

Strike, thanks to Reinhard and Rüdiger and the colleagues in Cergy for the research and to NEXOGEN for the patience
