Server issue

[wyvasi]

Hello!
After I update WCS from 1181 to 1264 edge server went unresponsive, I isolated the server(no traffic) but the cpu is still used at max. When it shouldn't be that way.

Good day.
Please clarify the folowing:
1. Is the problem persists after WCS restart?

systemctl restart webcallserver

2. If the server works normally after restart, how much time passed before the problem occurs?
If restart does not help, please collect a report using report.sh script and send using this form.

Last time I updated to this version I was getting some kind of out of heap memory error (cdn related) error spammed in logs. After one day server wouldn't respond anymore as cpu usage was >80%

Hello

We would need a report to proceed with investigation

Preparing an error report - Web Call Server 5.2 - EN - Flashphoner Documentation

docs.flashphoner.com

This report should show the cause of CPU load per CPU thread.
Before making report make sure jstack tool is working

Example:

jstack 2933

Here 2933 is the PID of server process
