Hi All,

```
Can we set Ulimit -l unlimited in RHEL servers as my servers running on production.es suggesting to give unlimited ulimit but my question is is it safe to enable Ulimit -l unlimited for root user on production servers?

```

Thanks  
phani

For root? Surely you're not running Elasticsearch as root?

Please don't run Elasticsearch as root. I can't imagine that there's any good reason for doing so.

Thank you for suggesting so if i run elasticsearch under elastisearch user so we can set ulimit unlimited for elasticsearch user instead of defining in root am I correct?
