02:19.59pabs3DocScrutinizer05: looks like massive load from a lot of web processes
02:20.22pabs3load average: 112.52, 109.11, 111.62
02:21.04DocScrutinizer05eeek
02:21.11DocScrutinizer05io?
02:21.21DocScrutinizer05or real cPU
02:21.27DocScrutinizer05CPU*
02:21.42DocScrutinizer05maybe check SMART
02:22.18pabs3aha, also there is a RAID recheck going on
02:22.21DocScrutinizer05or stop apache temporarily?
02:22.37DocScrutinizer05aaah that explains it, almost suspected that
02:22.44pabs3apache stopped already
02:23.36DocScrutinizer05I would also suspect one of the RAID drives has a nasty SMART report
02:25.15DocScrutinizer05though last (and only) time I had trouble with my RAID1, in the end a 50ct worth power Y-cable was the culprit
02:26.01pabs3SMART seems fine
02:26.03DocScrutinizer05it shown as sdb having more power cycles in SAMRT than sda
02:26.32DocScrutinizer05nothing in syslog during last 3 days?
02:27.14DocScrutinizer05maybe the controller
02:28.04DocScrutinizer05actually, what's a recheck?
02:29.23pabs3scans the raid1 to make sure both disks agree
02:29.46pabs3<PROTECTED>
02:29.52pabs3<PROTECTED>
02:33.43DocScrutinizer05so a frankenstein fsck
02:34.28DocScrutinizer05is that stuff scheduled, or maybe after N boots like fsck in fstab?
02:34.42DocScrutinizer05I mean, what triggered it?
02:34.52DocScrutinizer05the reboot?
02:36.19DocScrutinizer05that was like >49h ago already, and the recheck is at 6.7%
02:36.27DocScrutinizer0540*
02:39.37pabs3there is a cron job in mdadm and also a bunch of RAID1 devices
02:40.05pabs3one more RAID1 to check after the current one too
02:40.29pabs3it is possible the reboot triggered a check somehow too
02:41.23DocScrutinizer05aiui those checks should run in background and not slow down normal functional IO, no?
02:42.11DocScrutinizer05IOW the job runs only while system-IO idle
02:42.31DocScrutinizer05and gets suspended for all normal IO activity
02:43.27DocScrutinizer05which would explain why it's at 7% after 40h, *if* there was lots of normal system load like actually somebody hogging HTTP
02:43.27pabs3yeah that should be how it works, not sure tho
02:44.03pabs3starting apache again, lets see what happens
02:44.09DocScrutinizer05:-)
02:44.12pabs3<PROTECTED>
02:44.25DocScrutinizer05maybe check access logs, if there are any
02:47.16pabs3bing is walking the svn web interface...
02:47.57pabs3load is still okish
02:48.05pabs3<PROTECTED>
02:48.18pabs3I'll keep an eye on it
02:59.51DocScrutinizer05let me check mail RTT
03:01.22DocScrutinizer05wow, speed of light
03:02.04DocScrutinizer05swap hell?
03:02.18DocScrutinizer05not now, back when it was slooow
03:02.38pabs3probably
03:03.00DocScrutinizer05swap on webservers almost never makes sense in my experience
03:04.09DocScrutinizer05most of the webserver programs have some method of limiting the max memory they allocate
03:04.34DocScrutinizer05should be real RAM - N
03:16.55DocScrutinizer05on maemo the real RAM hogs were the scripting plugins, particularly php. They exploded when somebody mirrored the whole dynamically generated content
03:17.59DocScrutinizer05a 500MB per process were not unusual, and there were too many parallel processes for that php stuff
03:37.55DocScrutinizer05hmmm, my ssh login fails
03:38.33DocScrutinizer05thought that worked once
03:47.13DocScrutinizer05aah never mind, wrong user
