Same image for two live streams

Hello,

For a couple of months now, we are using AMS 5.0.3 to broadcast live camera feeds.

Yesterday we noticed an odd behavior: the subscribers of two different live streams (A and B) were getting similar images (A)!

I am wondering if somebody has already seen/heard about this situation and it's solution ?

It might also come from our server/client side scripts, but we can't figure it out!

Any comment or help would be appreciated,

Thanks
