Hi, I did experience a quite strange problem (at least for me) on the first node of our 2 node cluster. This is basically an imap/smtp/http proxy server. One of the imapd processes started to use a lot of cpu, memory... this morning. Oomkiller showed up and killed slapd, imapd, amavisd.... I then restarted those processes manually, and it went fine. A few moments later i got the following messages on my ssh terminal: kernel: Bad page state in process 'swapper' kernel: Bad page state in process 'swapper' kernel: page:c1032a40 flags:0x40000400 mapping:00000000 mapcount:0 count:0 kernel: page:c1032a40 flags:0x40000400 mapping:00000000 mapcount:0 count:0 kernel: Trying to fix it up, but a reboot is needed kernel: Trying to fix it up, but a reboot is needed kernel: Backtrace: kernel: Backtrace: kernel: Bad page state in process 'swapper' kernel: Bad page state in process 'swapper' kernel: page:c1032a40 flags:0x40000400 mapping:00000000 mapcount:0 count:0 kernel: page:c1032a40 flags:0x40000400 mapping:00000000 mapcount:0 count:0 kernel: Trying to fix it up, but a reboot is needed kernel: Trying to fix it up, but a reboot is needed kernel: Backtrace: kernel: Backtrace: The machine then completely locked, and did reboot (thanks to the watchdog). This server is a HP DL380G5 with 12Gb memory, 8 SAS Disks, .... a quite standard box. The $HOME directories are stored on a drbd (version: 0.7.24 (api:79/proto:74)) partition (with an XFS filesystem). The only 'non standard' thing I did use is a swap file instead of a swap partition. $ free total used free shared buffers cached Mem: 12471932 7420364 5051568 0 3984 6680868 -/+ buffers/cache: 735512 11736420 Swap: 393208 0 393208 $ grep swap /etc/fstab /var/tmp/swapfile swap swap defaults 0 0 Might this be the (or one of the) cause of this problem ? .config is available here: http://zenon.apartia.fr/stuff/config-2.6.22 Thanks Laurent
