Hi,
This is just the lines that contain the actual string "ERROR" but like I said, you need to look at the lines leading to it.
Also, you have "Lock is already seized", look at: https://github.com/kaltura/platform-install-packages/blob/Kajam-11.7.0/doc/kaltura-packages-faq.md#analytics-issues
which explains how to do basic troubleshooting and also removing locks.
