The same problems have been observed at 9.1-stable after the regular upgrade to stable/9. The system has been upgraded to 9.2-beta. There are problems with the network card igb: <Intel(R) PRO/1000 Network Connection version - 2.3.10(Quad Port Server Adapter), which is installed in the new HP DL380 g8 server. After the server is loaded everything seems to be fine but when the network load is high (about 500 users), there occur TCP sessions breaks (connections to exchange server, ssh, sql sessions break). I would like to point out that these problems are caused by a large number of TCP connections within the network and not by the volume of transmitted traffic or NAT load as the stable traffic 200 mb/s caused no problems at all.
In my opinion, the program configuration is completely workable, as it functions perfectly well on another device (FreeBSD 7.1 system) and there are no problems with the current system as well if the load is medium. Only high network load causes problems.
How-To-Repeat: Don't know, need huge trafic generator...

I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
At this point, FreeBSD 9 isn't supported anylonger. However, if these problems are still hapening. Let's dig in further and see what is actually going on.
