hi again,
i had to wait for my pppoe session to be terminated by the remote peer [1], and now it happened again with 2.6.11-rc5-bk2:
http://nerdbynature.de/bits/sheep/2.6.11/oom/oom_2.6.11-rc5-bk2_2.txt http://nerdbynature.de/bits/sheep/2.6.11/oom/lsmod_2.6.11-rc5-bk2 http://nerdbynature.de/bits/sheep/2.6.11/oom/config-2.6.11-rc5-bk2.gz
i wanted to see the application chewing up the most RAM so i was running "ps aux --sort=-vsz,-rss | head -n1" every 5sec and wrote it's output to a file:
http://nerdbynature.de/bits/sheep/2.6.11/oom/daily_stats-2.6.11-rc5-bk2.log.gz
but even when almost all swap is used up, mysqld ist still no#1 with 131928 KB VSZ, as always. still suspecting something wrong with pppd, the binary istself does *not* show up on the top-ten-memory-pigs.
real memory is almost always used up, but that's ok. i stripped it down to show only the timestamp and the "Swap: .. used" numbers:
http://nerdbynature.de/bits/sheep/2.6.11/oom/daily_stats-2.6.11-rc5-bk2_stripped.log.gz
as you can see, until "Sat Mar 12 01:05:51" 122MB swap was used, from then on swap-usage goes up until "Sat Mar 12 01:49:45", when all swap is in use. the system is unable to keep up with writing memory usage every 5 seconds, the next entry is from 12 "01:56:24" - 6 minutes after the first OOM message (i'm sure someone could feed this to gnuplot and make nice bars out of it - i can't)
where else could i look to actually *see* where the memory goes to?
somehow lost in kernel versions, Christian.
[1] "remote peer" aka "ISP". is there a way to "simulate" a "LCP terminated by peer" locally? otherwise i really have to wait 24h to trigger the bug. -- BOFH excuse #373:
