I think I am seeing something similar on a test box. I was loading up the box with 200k routes to do testing with. Kernel is default, save for a few unused drivers removed. If I take out options FLOWTABLE # per-cpu routing cache from the kernel, load avg is back to normal. This issue only seems to have come up in the past week or so as the previous kernel from ~8 days ago was OK. last pid: 6229; load averages: 2.00, 2.00, 2.00 up 1+17:33:02 09:39:31 141 processes: 7 running, 106 sleeping, 28 waiting CPU: 0.0% user, 0.0% nice, 22.2% system, 0.0% interrupt, 77.8% idle Mem: 98M Active, 2233M Inact, 187M Wired, 36K Cache, 112M Buf, 979M Free Swap: 8192M Total, 8192M Free PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND 22 root 76 - 0K 8K CPU3 3 41.5H 100.00% flowcleaner 11 root 171 ki31 0K 32K CPU2 2 41.5H 100.00% {idle: cpu2} 11 root 171 ki31 0K 32K CPU1 1 41.5H 100.00% {idle: cpu1} 11 root 171 ki31 0K 32K RUN 0 41.4H 100.00% {idle: cpu0} 869 root 4 0 64860K 64488K select 0 4:12 0.00% bgpd 11 root 171 ki31 0K 32K RUN 3 2:09 0.00% {idle: cpu3} 20 root 44 - 0K 8K syncer 0 1:00 0.00% syncer 12 root -32 - 0K 224K WAIT 1 0:47 0.00% {swi4: clock} 0 root -68 0 0K 80K - 2 0:03 0.00% {fw0_taskq} 1230 root 76 0 3348K 1160K ttyin 2 0:02 0.00% getty 863 root 96 0 24640K 24232K RUN 2 0:02 0.00% zebra 12 root -32 - 0K 224K WAIT 2 0:01 0.00% {swi4: clock} 14 root -16 - 0K 8K - 0 0:01 0.00% yarrow >_______________________________________________ >freebsd-stable@freebsd.org mailing list >http://lists.freebsd.org/mailman/listinfo/freebsd-stable >To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet since 1994 www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike
