Can't create more than one plugnmeet room at the same time

[Lyx52]

Currently I seem to be facing a problem where when I try to create two seperate rooms from moodle one gets created but the other one returns this error
Error: twirp error internal: could not create room: could not find any available nodes

This is the log of livekit when it happened:

It's livekit related problem:
2023-11-29T12:44:54.681Z INFO livekit service/server.go:300 waiting for participants to exit
The livekit was in progress to close that's why no room was created.

Also make sure your server have enough RAM for livekit + plugNmeet. Recommend at least 4GB & 2 CPU.

Currently the server is using:

I will checkout maybe my docker configuration is wrong but it should have access to all the resources

[jibon57]

Your livekit server was in progress to shutdown. May be you restarted it but it was waiting the users to exit first. During this situation you won't be able to create a new room. Your server's spec looks good.

Seems I might have found the problem, this health check was constantly killing livekit
