Created attachment 148599 [details] freebsd-soacceptqueue-minimum.patch Hello, The attached patch adds a new sysctl: kern.ipc.soacceptqueue_minimum It allows the system administrator to override the socket accept queue length. This is useful in cases where applications call listen(2) with too low of a socket queue length for a busy deployment, yet there is no application tunable for it. I look forward to any comments on the patch, we are using it in production on a large cluster already.
^Triage: somaxconn is now kern.ipc.soacceptqueue so patch needs an update and rebased, but someone can likely handle this anyway, if we want it.
