White recording on China server #753

Closed vnapastiuk closed 1 year ago

vnapastiuk commented 1 year ago

Description of the issue

When we start a video recording on a server in China, the first 30 seconds of the recorded video display a white-screen. After this first 30 seconds, the recording is correct. On another solutions with the same configuration we do not experience this issue; this happens only on a server in China.

If we empty the RAM cache, the first recording we make does not have the 30-seconds white screen; the recordings thereafter present the issue once more.

The Openvidu version is 2.20.0; Openvidu recordings version is 2.19.0-custom.

Additionally, when we start a video recording on the server in China, we have the following system error (not present in other solutions we have): Sep 27 21:30:20 localhost systemd[1]: docker-e08b6cebaa9942903914158f520c8c9d0d9bdbc6a370298629272b0d875a42d3.scope: Consumed 4.082s CPU time.

In the container of the video recording we have the following warning (this happens on other servers as well): ErrDocker-Thread

Here are the datas of the server in use: df-h

This is the RAM usage at the start of the video recording:

free-h

Any update on this? Could the problem be related to a resource consumption problem?

The issue was with a request to google fonts cdn our custom layout was doing, that was causing a connection timeout
