https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268910 --- Comment #4 from Brian Poole <brian90013@gmail.com> --- (In reply to Przemys=C5=82aw Lewandowski from comment #3) I apologize for wasting your time. I went back to my system which uses a cu= stom kernel config and began testing. My configuration file includes RSS which is not part of the GENERIC config: options PCBGROUP # Distributed Protocol Control Block Groups options RSS # Receive Side Scaling When I commented out RSS and PCBGROUP (required for RSS) and rebuilt the kernel, I had no trouble with ssh/nc TCP connections. However I use RSS acr= oss multiple NICs and with it included in the kernel I see instability with TCP (ssh inbound failing, wget outbound failing). --=20 You are receiving this mail because: You are the assignee for the bug.=
