Prateek , I've collected this from various sources and put it all together. Works fine for me, though I haven't yet dived into ELK:
----- You may verify the current soft limit by logging into the user that runs the Elastisearch JVM and issuing the following command: $ ulimit -Sn Finally, verify that Elasticsearch is indeed able to open up to this number of file handles from the max_file_descriptors value for each node via the _nodes API: $ curl localhost:9200/_nodes/process?pretty && echo ON LINUX Update the */etc/security/limits.conf* file and ensure that it contains the following two lines and all is well again: *username* hard nofile 65537 *username* soft nofile 65536 Of course, replace the '*username*' user name to reflect the user on your own machines that are running Elasticsearch. ON SOLARIS In Solaris 9, the default limit of file descriptors per process was raised from 1024 to 65536. ON MAC OS X Create or edit */etc/launchd.conf* and add the following line: limit maxfiles 400000 400000 Then shutdown OS X and restart the Mac. Verify the settings by opening a new terminal, and running either or both commands below: $ launchctl limit maxfiles $ ulimit -a You should see the maxfiles set to 400000 from the output of both of those commands. ----- Note that this is more of a Unix thing than an Elasticsearch thing. So if you are still having issues you may wish to ask on a newsgroup that specifically targets your operating system. Also note that it's not a good practice to run an application as root. Too much chance to wipe out something from which you could never recover, and all that. I remember than once our operations folks started ES as root, and then after that the data files were owned by root and the non-root ES user now had troubles starting with locking errors all over the logs. I ended up performing a recursive chown to the ES filesystem and when restarted as the non-root user all was well again.
