Hi, raise the no\_files of the user running elasticsearch, this is done typically adding to /etc/security/limits.conf the lines: elasticsearch soft nofile 64000 elasticsearch hard nofile 64000 test that it gets applied running: sudo -u elasticsearch -s "ulimit -Hn" If it doesn't get applied run: egrep -r pam\_limits /etc/pam.d/ and check that all pam\_limits.so are not commented out. if sudo -u elasticsearch -s "ulimit -Hn" returns 64000, but you still get the error on elasticsearch, you're probably running it through another program that doesn't support pam, a usual offender is supervisord. The only solution I know to this problem is to raise the nofile limit for the user running supervisord, but this will obviously raise the limit for all the processes running under supervisord, a non ideal situation. Hope it helps, Cheers, On Tue, Apr 5, 2011 at 10:35 AM, Enrique Medina Montenegro [e.medina.m@gmail.com](mailto:e.medina.m@gmail.com) wrote: > Hi, > I know the error message is understandable, but I'd like to understand why > and how to fix it.

Thanks a lot for your detailed response. Actually I'm using root for it, so I've set: ulimit -n 64000 And then running "ulimit -Hn" returns: [root@s1 ~]# ulimit -n 64000 [root@s1 ~]# ulimit -Hn 64000 Which I guess should be enough, right?

Nitpicking, to test your current limit try ulimit -Sn. -Hn gives you the hard limit, the limit that only root can change, -Sn gives you the current limit. The -Sn limit is what will be applied to the processes that you will start after the last change to the limits. So assuming ulimit -Sn gives you 64000, you still have to restart elasticsearch to get the new limit. Also, if you restart your box you will lose the 64000 limit, if you want to keep it after restarts you have to put it in /etc/security/limits.conf.
