Fair point Chris, I should have included log info in the original post. So in the solr logs, nothing at all. I think because solr doesn't get to the point of starting. In syslog I have --------- Dec 11 06:35:08 server solr[6822]: Waiting up to 180 seconds to see Solr running on port 8983 [|] #010#010#010#010#010#010 [/] #010#010#010#010#010#010 [|] #010#010#010#010#010#010 [/] (lots and lots of these removed) 010#010#010 [-] #010#010#010#010#010 Dec 11 06:35:08 server solr[6897]: Still not seeing Solr listening on 8983 after 180 seconds! --------- There was a warning about Ulimits, which doesn't seem to occur under Java 8: Dec 11 06:30:32 solr-dev solr[6266]: *** [WARN] *** Your open file limit is currently 1024. Dec 11 06:30:32 solr-dev solr[6266]: It should be set to 65000 to avoid operational disruption. Dec 11 06:30:32 solr-dev solr[6266]: If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false in your profile or solr.in.sh But I set that in /etc/defaults/solr.in.sh and it didn't help.
