Recently i encounter the error as i was trying to upgrade the Dspace from 6 to 7. During the migration process everything went fine until i give the solr restart command. please anyone in this forum could enlighten me to sort out the below error.

root@mseclibrary-V520-15IKL:/home/mseclibrary# su dspace
$ /opt/solr/bin/solr start
*** [WARN] *** Your open file limit is currently 1024.
It should be set to 65000 to avoid operational disruption.

profile or solr.in.sh
*** [WARN] *** Your Max Processes Limit is currently 31093.

Hi,

if you are still hitting this issue, it seems to be a Solr question more than a DSpace one.  Here's a guide though from ServerFault on how to possibly solve it in Solr: https://serverfault.com/questions/1023093/it-should-be-set-to-65000-to-avoid-operational-disruption
