Question / Help Dropping frames after some time

[P572]

Hello everyone.

We are having some trouble with setting up stream. It works perfectly fine for about 120-140 minutes, and after this starts dropping frames by thousands.
Here is what is going on in the logs:

While this text suggests that there is something wrong with internet connectivity, it feels really weird that it starts only after some time and always perfectly fine at the stream start.
Here what we have tried:
1)Streaming from another computer - the very same thing happens there, so network card and stuff should be fine.
2)Changing server - nothing changes, so it is probably not the case.
3)Rebooting modem and router - nothing changes, so it is probably fine as well.

Considering that it works fine at the start, OBS configuration should be fine.

Any suggestions?

Not sure unfortunately. This isn't something we can really help out with. I can tell you that it's very unlikely to be the program's fault, because if there were an actual problem with it everyone would get it and I'd be swimming in forum posts and emails about it.

Thank you for answer Jim!

After prolonged investigation it turned out that ISP is complete idiot and chokes upward connection if there is a lot of traffic over the couple of hours. So yes, it doesn't seem to be OBS issue.
