Transmission listen queue

[Pertti Kosunen]

Jan  3 10:27:43 servername kernel: sonewconn: pcb 0xfffff80010936188: Listen queue overflow: 193 already in queue awaiting acceptance (2 occurrences)

% netstat -LaAn
Current listen queue sizes (qlen/incqlen/maxqlen)
Tcpcb  Proto Listen  Local Address
fffff80006ab5400 tcp6  0/0/128  *.55555
fffff80006907000 tcp4  0/0/128  *.55555

How can I increase the listen queue for transmission-daemon(1)? I did add kern.ipc.somaxconn=2048 to /etc/sysctl.conf as some howto recommended, but netstat(1) still shows maxqlen 128.

10.1-RELEASE-p3

(0xfffff80010936188 was transmission-daemon(1), I restarted it before copy/paste of netstat(1).)

Wrong name. This is what you are looking for and the default is 128 as you've already seen.
sysctl -d kern.ipc.soacceptqueue

kern.ipc.soacceptqueue: Maximum listen socket pending connection accept queue size

Note that this does not affect jails, which are stuck with the compile-time default of 128: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219655
