Hi, I have a application run by a normal user communicating with the server with UDP. It crashes very occasionally, like once per week, due to EACCES when sending a UDP packet. According to the manpage (https://man.openbsd.org/OpenBSD-6.9/sendmsg.2#EACCES), the reason might be either being blocked by PF or sending to a broadcast address. I can confirm the packet was not sent to a broadcast address. However, I cannot figure out what rule could block the connection occasionally either. The application can be brought back online without changing any configuration. Does anyone know what might fix this? I can also rewrite the code to make it ignore the error and keep trying but that might not be a proper solution. Running it as root might not be a good idea, too.
It happens since OpenBSD 6.8. Now I’m running it on 6.9. The application is written in Rust. Siegfried siegfried.le...@gmail.com
