As an addendum: For me it looks as if the cores are simply not loaded, although
the configuration is correct and has not been changed (apart from the
enlargement of the heap).

I set the heap to 8g but this doesn't have any effect and the problem is still
the same.

Just keep in mind that the total memory should be much more than the heap to
leverage Solr file caches. If you have 8 GB heap probably at least 16 gb total
memory make sense to be available on the machine .
