https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219655 Bug ID: 219655 Summary: TCP Connection Limit Error - sonewconn: Listen queue overflow Product: Base System Version: 11.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: john.leo@gmail.com I'm currently running FreeNas 11 RC1. I've edited the tunables for this item kern.ipc.soacceptqueue to allow for 2048 connections, but it doesn't propagate to the jails on my system. Below is the error I received saying the listen queue is full.
