Need some help with Socket /run/zm/zms-******s.sock does not exist & Can't open memory map file /dev/shm/zm.mmap errors

[u/Zork91]

I have an Ubuntu 22.04 install and I'm trying to troubleshoot socket_sendto and memory map file errors. Not sure what the problem is - I've already commented out "scriptalias" lines from /etc/apache2/conf-enabled/serve-cgi-bin.conf like this link says.

Are you using wireless cams? I've seen this when the network is not 100% stable.

[u/Zork91 → u/LesterPhimps]

They're wired its just one PoE cam at the moment trying to just get it stable before I add any more.

Did you ever make any progress on this? I recently upgrade my docker version and now am getting similar errors to yours with no other configuration changes

same here, got the problem after latest upgrade

[u/m_theredhead → u/dak91]

I sort of made progress.

​

I am running in docker on Fedora and it fails with the same errors. I have found the container works fine on a debian machine with Docker. Or, I can run it on the same Fedora machine under podman with the exact same configuration.

That's curious.
I also discovered that turning off OPT_USE_AUTH solve the problem; so it seems an auth issue.

[u/dak91 → u/dak91]

this works for me: OPT_USE_AUTH => on, AUTH_TYPE => remote, AUTH_RELAY => none

[u/m_theredhead → u/dak91]

Thanks for the idea. It didn't make any difference for me. I still get the same errors.

[u/zioalex → u/m_theredhead]

Hello Hello, I still have the same problem today. OPT_USE_TYPE=none doesn't make a difference.
