Thanks for the amazing project @AlexxIT!!

I think I'm experiencing the same or similar panic. I hope the following information helps.

same exact here, it seems to happen most often when go2rtc is started during boot. I added a sleep time of 15 seconds to my start script before launching go2rtc, and it seems to not happen anymore. I also seemed to have gotten the same crash on 1.9.8, but not on launch - about 40 days into running

@Fohdeesha your panic from another issue

AlexxIT avatar Jul 25 '25 13:07 AlexxIT

@AlexxIT interesting, how can you tell, the slightly different address for the violation? Is there a relevant github issue for mine?

Fohdeesha avatar Jul 25 '25 21:07 Fohdeesha

This issue about bufio.(*Writer).Flush panic. Your issue about v2.(*MultiUDPMuxDefault).RemoveConnByUfrag panic.

I have this panic too
