Re: [OmniOS-discuss] igb0 'hangs'
Perhaps iperf can help you for identify this problem. When i have this sort of failure under Solaris, i use iperf for load bandwidth and set different TCP window size. During the test, i use snoop for see at what moment the problem appear come. 2014/1/20 Tobias Oetiker > Today Steffen Kram wrote: > > > Hi Tobi, > > > > I had a similar problem a while ago, when I was resetting the > > maxbw property without taking the interface down.

Re: [OmniOS-discuss] igb0 'hangs'
Hi Tobi, I had a similar problem a while ago, when I was resetting the maxbw property without taking the interface down. The global zone could not communicate over that interface anymore, while the zones where all happy. Taking the interface down and up again solved my issue, too.

[OmniOS-discuss] igb0 'hangs'
I just had an odd thing happening to my r151008 server. It suddenly stopped communicating over its igb0 interface ... Upon further investigation I found: a) several KVM guests talking over the same physical interface were still happily chatting b) logging into the guests and trying to reach the server over that route did not work either. c) accessing the server via the hardware console revealed that it was working and did not seem to realize that igb0 was having a problem. At least dmesg did not show anyithing interesting. once I did # ipadm down-addr igb0/v4static # ipadm up-addr igb0/v4static the interface started working again ... any idea what has happened here ? cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland http://it.oetiker.ch t...@oetiker.ch ++41 62 775 9902 / sb: -9900 ___ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss
