Hello Özbek

Is this a production server? I mean do you use this server as online server at your university?

How many online users do you have in that server?

Curious to the contents of the events.xml,  Not all events are needed to create the recording…   Should find out what is making the events.xml large?

 

Can you see in the raw folder events.xml… what is happening.

 

May be possible to strip out the offending events, and try to build the recording.

 

Regards,

Stephen.

Approximately maximum of 150 users on the server.  Parallel 2 or 3 sessions. But only one instructor session makes problem. Another instructor at the same time didn't any publish problems.

Hello Özbek

Beside your problem, I think,  the most important part is that your server is so weak for this number of online users. You should upgrade your server and your problem will be solved.

I can help you to config a new server. If you want, please let me know.

Thanks for your help proposal. I have 130 BBB servers and best fit server configuration for our use cases. Because my participants' number doesn't exceed 150 and instant parallel sessions number 200.

So you are using clustering. I had the same problem in one of my servers. My problem was something like you and I had an incomplete event.xml file. I think the best option is a fresh installation and then transferring your meetings to that.

What is your LMS? Do you use moodle or your own LMS that is using BBB API?
