[GeoNode-users] Issues with mosaics in GeoNode

so you are using GeoNode 2.10.3 and GeoServer 2.15.4 I guess, is that
First of all, as soon as possible update GeoServer with the same version
The WARs have been rebuilt recently with some updates of GeoServer
Secondly, are you trying to create the mosaic by using the shapefile index?
Try to create the "datastore.properties" and let GeoServer create the index
on the DB instead.
I recently configured a mosaic with more than 120K granules and it worked
A warning here. When you create the store, the first time, GeoServer will
remain blocked for a long time, until he finished scanning all the
granules. Even if you have some strange page back on the gui or some odd
behavior, don't worry about it.
Finally, there's a method on GeoNode "_invalidate_geowebcache_layer" which
is called when you create a Layer and mostly when you update the style.
Currently, the behavior is trivial, he just invokes the method every time
you update the style. It probably could be improved.
