We run 2 virtual event websites which are based on WordPress but have a large proportion of custom coding.
We are using the current Webinar SDK on the sites and up to now have not really had any issues with the exception of viewers using Apple products and sound issues
Today we had an event and as soon as the stream went live at 09.28 GMT, it crashed the server. I had to restart PHP and Apache (not knowing which had failed) to bring everything back. I have added a link to a snapshot of the server monitor.
The webinar would have had approx 450-500 people.
The server is very high spec
The site is running PHP 7.4.3 as Dedicated FPM application served by Apache with very healthy settings
Why did this happen? Any advice?
What is the limit for viewers of embedded webinars?
We have done research plenty of times and it seems that Zoom webinar puts very high demand on CPU
I submitted your info to our support staff to (18287861). Unfortunately, our support article does not speak to your specific concerns, so hopefully we can get some more detailed specs to help you successfully host Zoom webinars with MSDK of that size!
