Hello,
I ran accros an awkward situation where is collect all ~7.000.000 distinct
values for a field via facetting. To keep things optimized and reduce memory
consumption i don't do setFacetLimit(-1) but a reasonable limit of 10.000 or
100.000.
To my surprise, Solr just stops or crashes. So, instead of decreasing the
limit, i increased the limit to a 1.000.000! And it works! The weird thing is
that with a limit of 100.000 or 200.000 and a heap of 3.5 GB, Solr stops. But
with a limit of 1.000.000 and a reduced heap of 2.5 GB, it just works fine.
When it fails, it some times doesn't crash, but throw
396882 WARN (NIOServerCxn.Factory:0.0.0.0/0.0.0.0:9983) [ ]
