We are seeing 30% or more packet loss (from utcapture) on Rays after applying the 27-May-2008 Solaris 10/x86 recommended patch cluster on a Sun X4200.
We had recently moved away from Cisco switches since we could not resolve packet loss problems there, and were enjoying exceptional performance with a direct connection to the server via an inexpensive Netgear switch. Users trigger the packet loss problem with flash video or via "weather movies". Current packet loss is much worse than anything observed before patching, regardless of wiring. Now of course I regret patching, but the motivation was 127128-11 which addresses a recent security alert. To add to the injury, the sshd patch in the cluster breaks X11 forwarding on machines with only ipv4. We used a workaround of enabling an ipv6 lo0. I don't have evidence that this is related to the packet loss problem, however. I'd be thrilled to hear suggestions or similar experiences. When we were using Cisco switches, we tested the NewtBW throttling mechanism. This helped a little on the Ray 1, but did nothing for our Ray 2. We have SRSS 3.1 with 120880-07. -- Darrel Hankerson _______________________________________________ SunRay-Users mailing list [email protected] http://www.filibeto.org/mailman/listinfo/sunray-users
