Reliable streaming

[Dipesh Dulal]

Hello community, 

With a single streaming server instance. I have seen the server crash and all the stream viewers and streamers are interrupted. How can I maintain reliable streaming setup ? 

Do we require ant media cluster to make it reliable ? Or are there some settings that need to be used for the server ?

Hi Dipesh.dulal,
Could you provide reproduce scenario please?

Best Regards,

Enes.

Thank for the reply. 

This is a general question. For instance;

I have been receiving this error that crashes the ant media server instance Enterprise Edition 2.3.2 20210422_0456. In previous version it was some other problem. 

So I am not talking about exact problem but to improve availability of the system and make it work even in case of crashes. Eg; 

Publisher A is publishing the stream, Viewers are watching the stream suddenly server crashes all of them are disconnected and provides bad user experience.

We want to prevent disconnection in case server crashes. (Or improve availability of the server)  ‍♂️

Clustering probably helps in this case since it provides redundancy.
