Until today all has been fine, system is usually 80-90% idle with a load of 0.2-0.3 all the time. Suddenly it's consistently only 40-50% idle with a load of 1.5-2.5. top shows nothing except that the load is coming as system processes, 30-40% where it used to be only 2-3%. However, running top with -S still shows nothing. I don't recall doing anything that would explain this. What can I look for to explain this sudden increase in system load? I've included a snapshot of top below George --------------------------------------------------------------------------------------------------------------- last pid: 29263; load averages: 1.88, 1.94, 1.81 up 0+15:03:45 21:42:04 701 processes: 22 running, 600 sleeping, 79 waiting CPU states: 10.3% user, 0.0% nice, 40.0% system, 1.0% interrupt, 48.8% idle Mem: 277M Active, 1332M Inact, 211M Wired, 69M Cache, 112M Buf, 113M Free Swap: 748M Total, 748M Free PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND 11 root 106 0 0K 12K RUN 3 605:38 64.65% 64.65% idle: cpu3 12 root 105 0 0K 12K RUN 2 537:46 58.84% 58.84% idle: cpu2 13 root 105 0 0K 12K RUN 1 513:30 57.08% 57.08% idle: cpu1 14 root 105 0 0K 12K RUN 0 518:14 55.57% 55.57% idle: cpu0 978 root 96 0 15844K 9264K CPU2 3 1:27 0.10% 0.10% httpd 459 bind 119 0 51860K 50312K RUN 1 19.1H 0.05% 0.05% named 35 root -68 -187 0K 12K RUN 0 7:16 0.05% 0.05% irq22: fxp0 --------------------------------- Yahoo!
