An exceptionCaught() event was fired... Too many open files

So? The solution is to change the limit but for the user "root"?

I don't know what is happening but it is a mess :-)
I don't why, but the process which run Traccar not change his limits.
PD. I'm using an AWS EC2 with Debian.

Limits set for the system

Limit for user root

Limits for process which is executed by root

WOW!! It works!!!

I did this change!
Modify /etc/systemd/user.conf and /etc/systemd/system.conf with the following line:
DefaultLimitNOFILE=100000

I think this is the correct way.
At the end, what matters is that the process that Traccar executes is the one that increases the limits.

Excellent! Good to know this. Regards

I think it is a matter of PAM and systemd, according the system is the configuration, please check this URL:
