redis have no pressure on it and resources are not used excessively, I tried to remove appendonly but it didn’t give me the solution.

How are you specifying the Redis config info to the image?

It looks like maybe you aren’t using REDIS_HOST_PASSWORD? If you don’t, it will not get passed to the PHP config for session.save_path via the image’s entrypoint.

See Nextcloud Docker: Redis

Hello, For now I dont have a redis password.
and I configured the host name and other details in config.php for NC.
