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'

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

Mem: 12471932 7420364 5051568 0 3984 6680868

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
