High CPU usage when idle

Channels DVR Server Troubleshooting
#1

channels-dvr process is using ~25% CPU when idle

This is happening on 2 of 3 Channels DVR docker containers.
All are at version 2021.07.29.2129.
1 uses an HDHR Prime source and shows ~25% CPU

I have shut down and restarted the containers. No help.

Now all 3 containers are doing it.
Here's the Synology Resource monitor showing 2 & 3

UPDATE: It's not just in a container. I migrated #1 to the new Synology DSM 7.0 package and I'm seeing the same CPU usage.

Possible fix in v2021.07.30.0452 (still uploading). Let me know what you observe with that build.

Thanks!
2021.07.30.0452 Looks good so far.
CPU usage is now close to 0.
Will see how it looks in the morning.

I saw high CPU use also yesterday on my iMac, sometimes 100% CPU usage. Now back to 0% at idle on .0452
