August 29, 20232 yr I have problems on my Unraid 6.12.3 server. A few hours or days after a fresh restart, nginx hangs and the web interface can no longer be accessed. However, SSH works. I entered nginx via SSH and received the following output: root@Violet:~# nginx nginx: [emerg] bind() to unix:/var/run/nginx.socket failed (98: Address already in use) nginx: [emerg] bind() to 127.0.0.1:80 failed (98: Address already in use) nginx: [emerg] bind() to 192.168.68.57:80 failed (98: Address already in use) nginx: [emerg] bind() to 127.0.0.1:443 failed (98: Address already in use) nginx: [emerg] bind() to [::1]:80 failed (98: Address already in use) nginx: [emerg] bind() to [2a01:598:c834:6377:baae:edff:fe3b:efe3]:80 failed (99: Cannot assign requested address) Message from syslogd@Violet at Aug 28 10:34:42 ... nginx: 2023/08/28 10:34:42 [emerg] 11962#11962: bind() to unix:/var/run/nginx.socket failed (98: Address already in use) Message from syslogd@Violet at Aug 28 10:34:42 ... nginx: 2023/08/28 10:34:42 [emerg] 11962#11962: bind() to 127.0.0.1:80 failed (98: Address already in use) Message from syslogd@Violet at Aug 28 10:34:42 ... nginx: 2023/08/28 10:34:42 [emerg] 11962#11962: bind() to 192.168.68.57:80 failed (98: Address already in use) Message from syslogd@Violet at Aug 28 10:34:42 ... nginx: 2023/08/28 10:34:42 [emerg] 11962#11962: bind() to 127.0.0.1:443 failed (98: Address already in use) Message from syslogd@Violet at Aug 28 10:34:42 ... nginx: 2023/08/28 10:34:42 [emerg] 11962#11962: bind() to [::1]:80 failed (98: Address already in use) Message from syslogd@Violet at Aug 28 10:34:42 ... nginx: 2023/08/28 10:34:42 [emerg] 11962#11962: bind() to [2a01:598:c834:6377:baae:edff:fe3b:efe3]:80 failed (99: Cannot assign requested address) I checked with netstat which processes use those ports already, but came out it's just nginx itself: root@Violet:~# netstat -tulpen | grep :80 tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 0 29063 9008/docker-proxy tcp 5 0 127.0.0.1:80 0.0.0.0:* LISTEN 0 15172 3285/nginx: master tcp 16 0 192.168.68.57:80 0.0.0.0:* LISTEN 0 15173 3285/nginx: master tcp6 0 0 :::8000 :::* LISTEN 0 51604 15985/portainer tcp6 0 0 :::8080 :::* LISTEN 0 29066 9016/docker-proxy tcp6 0 0 2a01:598:c834:6377:b:80 :::* LISTEN 0 15176 3285/nginx: master tcp6 0 0 ::1:80 :::* LISTEN 0 15175 3285/nginx: master root@Violet:~# netstat -tulpen | grep :443 tcp 0 0 127.0.0.1:443 0.0.0.0:* LISTEN 0 15174 3285/nginx: master tcp6 0 0 ::1:443 :::* LISTEN 0 15177 3285/nginx: master I tried to stop all nginx-processes: /etc/rc.d/rc.nginx stop Shutdown Nginx gracefully...

After booting up, everything runs as usual again. But I think this is another problem, which is not necessarily part of the nginx problem. Diagnostics are being created at the moment, I'll upload them together with syslog files afterwards. Can somebody help me here with this problem(s)? Thanks a lot!
August 29, 20232 yr Author Syslog and diagnostics attached. I rebooted the server now. I can't create complete diagnostics as the diagnostics process hangs up during log creation (copied from Webinterface): top -bn1 -o%CPU 2>/dev/null|todos

September 4, 20232 yr I'm having the same issue nginx: [emerg] bind() to 0.0.0.0:81 failed (98: Address already in use) nginx: [emerg] bind() to [::]:81 failed (98: Address already in use) restarting the docker fixes it but this happens daily
September 4, 20232 yr Author I made the update to 6.12.4 and this error did not appear again. But the server is still hanging up completely with 100% CPU and not responding to anything anymore, until I restart. This happens once a day.
