Session time outing. Bizarre that happens only on link with igb driver, while bce has no issues (server with two nics one 4ports igb and one 2ports bce). tcpdump on igb link even do not show packets arriving while I see them sent from the other end. The same link plugged to the bce works. What else can be done to debug this ? 27.11.2011, 21:59, "Kevin Oberman" : > On Sun, Nov 27, 2011 at 7:10 AM, Darren Baginski wrote: > >> šHi! >> >> šI'm having issues with OpenBGPd šopenbgpd-4.9.20110612_1 running on šFreebBSD 9-PRERELEASE. >> šBGP sessions flap for no reason every ~4hours, bgp sessions itself receive only default form cisco router. >> šFreeBSD 8.2 is not affected. >> šHow can I troubleshot this? > > Start by looking at the logs on both ends.
