Title: Unbound Error
Post by: spetrillo on September 24, 2026, 03:37:03 PM
Hello all,

I am troubleshooting an Unbound issue. When I restarted Unbound from the cli it spit out the following:

[1790256794] unbound[48659:0] warning: setsockopt(..., SO_SNDBUF, ...) was not granted: No buffer space available
[1790256794] unbound[48659:0] warning: so-sndbuf 4194304 was not granted. Got 57344. To fix: start with root permissions(linux) or sysctl bigger net.core.wmem_max(linux) or kern.ipc.maxsockbuf(bsd) values. or set so-sndbuf: 0 (use system value).


I checked the kern.ipc.maxsockbuf tunable and it is set to 4262144.

Is this something I should be worried about?

Thanks,
Steve
