Thanks, Nick & Hoss. I am using the exact same machine, have wiped out
solr 5.5.0 and installed solr-6.0.0 with external ZK 3.4.8. I checked the
File Description limit for user solr, which is 12000 and increased to
52000. Don't see "too many files open..." error now in Solr log but still
Solr connection getting lost in Admin panel.
Let me do some more tests and install older version back to confirm and
will share the findings.
Thanks,
Susheel
