Hi everyone,

I am getting an error "max number of threads [1024] for user [elasticsearch] is too low, increase to at least [2048]"

I opened [this](https://www.elastic.co/guide/en/elasticsearch/reference/master/setting-system-settings.html#limits.conf) manual and tried the following:

After trying:  
"sudo su  
ulimit -n 65536  
su elasticsearch "  
I get an error:  
"This account is currently not available."

After trying to add "elasticsearch - nofile 65536" to /etc/security/limits.conf the problem doesnt move.

After trying to add  
"[Service]  
LimitMEMLOCK=infinity"  
to "/etc/systemd/system/elasticsearch.service.d/elasticsearch.conf" the file does not save.

currently I am stuck on starting the ES.

Will be grateful for any help,  
Many Thanks,  
Tomer Zaks.

You want `nproc`, not `nofile`, and you shouldn't increase it that high, 2048 like the message says will be plenty.
