Dear forum,
I've been trying to diagnose a packetloss problem on one of my FreeBSD servers. Its running 6.2-RELEASE-p7 amd64 and the issue is with the nge0 interface.
(some data masked due to privacy reasons)
The first step i tried was disabling hardware checksum offloads, as sometimes these do not work correctly. However, the follow command appears to have no effect at all:
It doesn't yield any error message, but after the command ifconfig still shows rxcsum and txcsum to be enabled. What am i doing wrong here? The interface is using aliases because its hosting several jails. Could this be related to my issue?
The packetloss seems to be about 12%. It prevents me from updating the portstree for example, although SSH does work, with some 4-5 second of pause sometimes because of some lost packets. It appears the size of the packets may be relevant; smaller packets usually get through. But this is just a guess.
Anyone can point me in the right direction for diagnosing this?
