WCPS requests going through the general petascope servlet fail, it seems that the coverages are not loaded from the database.

It works fine sending WCPS requests to the dedicated WCPS servlet, e.g. ​http://localhost:8080/petascope/wcps

To reproduce try:

wget --post-data='query=for c in (mr) return AvG(c)' http://localhost:8080/petascope

working

wget --post-data='query=for c in (mr) return AvG(c)' http://localhost:8080/petascope/wcps

A sleep of few seconds after starting rasmgr is necessary before starting the rasservers, otherwise it fails sometimes.

Just found out that rasimport in 8.4-rc2 causes a segmentation fault when attempting to create a new cube:

command used:

rasimport -d test/ -coll test -3D top -shift 0:0:150500 -csz 1

Same command with same data worked on 8.4-rc1 though.

TIFFs used for testing are attached.
