Before I rebooted the machine, we also got these messages. The machine

Dear All
Our Kernel-Version:
Linux thinpower 2.6.29 #5 SMP Sun Apr 5 20:04:08 UTC 2009 x86_64
Intel(R) Xeon(R) CPU E5450 @ 3.00GHz GenuineIntel GNU/Linux
This morning our Server ran out of memory and had to be hard rebooted.
The system hast 32 GB or memory and 4 QuadCore Xeon CPUs.
/var/log/kernel/current tells us the following:
