I’ve been constantly having the error “system: cannot reserve inbound connection: resource limit exceeded” show up in my logs, while my node seems to be working fine (at least), I want to know if this is an issue and how to fix it. Also if anyone knows how to fix the UDP receive buffer error (note that the medium instructions don’t seem to work on openbsd) that would be helpful.
Here is what my ipfs node prints when running (notes use ][ ):
Kubo version: 0.17.0
Repo version: 12
System version: amd64/openbsd
Golang version: go1.19.1
2022/12/05 19:06:59 failed to increase receive buffer size (wanted: 2048 kiB, got 0 kiB). See https://github.com/lucas-clemente/quic-go/wiki/UDP-Receive-Buffer-Size for details. [Pretty sure this is an unrelated error]
