Hi! With Linux 3.2, no sync daemon, only using DR, conntrack disabled, about 100k connections in IPVS, we get 100% CPU usage, all in soft interrupts. A few seconds before, CPU usage was very low. We are able to get back to normal by reducing the traffic going through the box. Once the problem is resoved, CPU usage becomes low again. So, it seems that we hit some "ceiling".
Are there known problems with IPVS and Linux 3.2? -- Follow each decision as closely as possible with its associated action. - The Elements of Programming Style (Kernighan & Plauger) _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-requ...@linuxvirtualserver.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users
