Hey @sinianzhiren What was the issue and how it got resolve?

[liudonghua123]

@sinianzhiren Hi, I encountered the same problem. How did you solved?

[liudonghua123]

I found I have some configs in /etc/docker/daemon.json.

{
        "default-ulimits": {
                "nofile": {
                        "Hard": 64000,
                        "Name": "nofile",
                        "Soft": 64000
                }
        }
}

So I increased the ulimits and it fixed.

[root@localhost docker]# docker run -it --rm supabase/realtime:v2.25.66 sh
Setting RLIMIT_NOFILE to 100000
/app/limits.sh: line 6: ulimit: open files: cannot modify limit: Operation not permitted    
[root@localhost docker]#      
[root@localhost docker]# vim /etc/docker/daemon.json
[root@localhost docker]# 
[root@localhost docker]# service docker restart
Redirecting to /bin/systemctl restart docker.service
[root@localhost docker]# 
[root@localhost docker]# docker run -it --rm supabase/realtime:v2.25.66 bash
Setting RLIMIT_NOFILE to 100000

Hey, running into this error as well -- that field isn't in the new daemon.json, nor is it in the daemon.json.coolify. I added it manually, but it doesn't appear to have fixed the issue. will update if i figure it out.
