This "Limited Transmit" option, is that configurable somewhere and does that work-around the bug (a quick grep tcp on sysctl -a doesn't yield something recognizable)? Seen this this morning while doing a `cvs -d/home/ncvs update src', logged in via ssh in a GENERIC kernel of 2004-01-10. This was via a chello Netherlands cable connection - an ISP famous for it's high bandwidth and equally high packet loss, so it fits the profile. I'll try Andre's patch regardless, but if it doesn't work, it would be nice if there's an alternative (maybe mention that in UPDATING as well). -- Melvyn ======================================================= FreeBSD sarevok.idg.nl 5.2-CURRENT FreeBSD 5.2-CURRENT #3: Tue Dec 30 14:31:47 CET 2003 root@sarevok.idg.nl:/usr/obj/usr/src/sys/SAREVOK_NOAPM_NODEBUG i386 ======================================================= [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQBADmUwOv9JNmfFN5URAreOAKC1fydKZt+BhvqGoJ6/YSR1D4Pm0QCcCwze biiDGlNCICEBWDXX7pWsCIs= =2O/O -----END PGP SIGNATURE-----
