Beginning of this discussion: http://comments.gmane.org/gmane.linux.network/341427 Quick summary: starting with kernel 3.18 or commit 55601c9f24670ba926ebdd4d712ac3b177232330 am335x (at least BBB and some custom boards) stalls at high network load. Reproducible via nuttcp within some minutes nuttcp -S (on BBB) nuttcp -t -N 4 -T30m 192.168.1.235 (on host) As Felipe Balbi suggested, I tried both 4.8.3 and 4.9.2 toolchains, but both show the same behavior. Linux version 3.18.0 (user@user-VirtualBox) (gcc version 4.8.3 20140320 (prerelease) (Sourcery CodeBench Lite 2014.05-29) ) #6 SMP Mon Dec 8 22:47:43 CET 2014 Linux version 3.18.1 (user@user-VirtualBox) (gcc version 4.9.2 (Buildroot 2015.02-git-00582-g10b9761) ) #1 SMP Mon Dec 29 09:22:29 CET 2014 Let me know, if you can reproduce this issue.
