wow, just hung my machine up solid twice in about a half hour period ... I just upgraded my machine to a Dual-PIII 700 on an ASUS P2B-D motherboard ... everything has been running great the past 2 days, things just fly along, hardly ever see the load average rise about 1 ... today, I'm working on improving stats generation for my virtual hosts and wrote a simple script that goes through and runs webalizer against any domain that has had activity since the last run ... basically it checks a domain, runs webalizer in the background and goes off to the next one ... as soon as I start the script, the load avg climbs relatively quickly (last one I saw was 26 and rising), the machine gets more and more lag'd until it just locks up solid ... I'm running remotely, and have the serial console configured, but altho I can see the machine boot, get to single user mode and all that, as soon as I goes multi-user my keyboard no longer works, so I can't get to DDB ... I'm running 4.1-STABLE code as of Monday night ... I hate to do it, but I'm going to try and kill it once more with top running and see if anything odd comes up in there ... yup, third time is the charm ... all when I do my stats run. top shows: last pid: 13913; load averages: 71.25, 37.03, 15.564 up 0+00:09:43 14:52:23 262 processes: 2 running, 258 sleeping, 2 zombie CPU states: 37.1% user, 0.0% nice, 45.3% system, 1.3% interrupt, 16.3% idle Mem: 368M Active, 42M Inact, 53M Wired, 2244K Cache, 61M Buf, 37M Free Swap: 2047M Total, 602M Used, 1446M Free, 29% Inuse, 12M In PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND 13513 corey 2 0 2220K 1324K select 1 0:03 32.17% 11.67% top 13512 jeff 2 0 2220K 1316K select 0 0:03 31.77% 11.52% top 918 scrappy 64 0 2208K 704K CPU1 1 0:11 26.25% 9.52% top 8568 root -22 0 1026M 218M swread 0 0:16 4.40% 4.39% webalizer 610 root 2 0 2916K 1128K select 1 0:12 2.15% 0.78% named 13535 nobody -6 0 3724K 3128K pipdwt 0 0:00 3.01% 0.78% perl 13534 nobody -6 0 3724K 3128K pipdwt 1 0:00 2.82% 0.73% perl 1485 nobody 2 0 8956K 904K sbwait 0 0:01 1.75% 0.63% libhttpsd. 14003 root 64 0 864K 508K CPU0 0 0:00 0.00% 0.00% sh I have 768Meg of RAM on this machine, and >2gig of swap space ... I actually saw a loadavg of 90 while watching, but couldn't capture it ... does 4.1-STABLE have any known problems with not being able to handle "bursts" of processes? *raised eyebrow* I'm suspecting the other lock(s) were just high load too, now that I watch top ...
