This happens with current some (big) time ago. See here vmstat (vm mode) output: 3.3%Sys 0.8%Intr 95.9%User 0.0%Nice 0.0%Idle %ozfod 128 rtc irq8 | | | | | | | | | | | daefr 66 cbb0 pcm0+ ==>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> prcfr 1 ata0 irq14 33 dtbuf 47 totfr ata1 irq15 Namei Name-cache Dir-cache 69694 desvn react Calls hits % hits % 15144 numvn pdwak 1259 1259 100 9063 frevn pdpgs intrn 99.5% CPU used in user space. now top output (sorted by CPU): last pid: 2024; load averages: 1.03, 0.65, 0.40 up 0+01:28:34 11:38:50 120 processes: 4 running, 116 sleeping CPU states: 95.7% user, 0.0% nice, 3.5% system, 0.8% interrupt, 0.0% idle Mem: 589M Active, 209M Inact, 146M Wired, 512K Cache, 111M Buf, 46M Free Swap: 1200M Total, 1200M Free PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND 927 root 1 97 0 52084K 28172K select 1:02 2.98% Xorg 1128 vova 1 96 0 21172K 13676K select 0:10 0.98% metacity 1252 vova 1 96 0 38024K 29884K select 1:56 0.63% skype_bin 1386 vova 11 126 0 516M 470M RUN 3:42 0.00% evolution-2.6 1134 vova 3 20 0 21540K 13496K kserel 1:38 0.00% gkrellm 1113 vova 1 96 0 19592K 9604K select 0:17 0.00% at-spi-registryd 1327 vova 1 96 0 34464K 24668K select 0:10 0.00% sim 1323 vova 1 96 0 24552K 17212K select 0:09 0.00% cpufreq-applet ... No any idea who eats these 95.5% of CPU time. Same picture on vmstat's pigs screen. I know that this process is actually evolution, and if I kill it system load drops, but why it is not shown by top (and other). Any hints about it ? -- Vladimir B. Grebenschikov vova@fbsd.ru
