I want to give some update here: 1. We finally hit the problem on a third system, with a total different setup and hardware. However, again high I/O load caused the problem and the affected filesystems were mounted with noatime. 2. I installed a recompiled kernel with just the two line patch from Richard Kennedy (http://lkml.org/lkml/2007/8/2/89). That system has 5 days uptime now and counting. I believe the patch fixed the problem. However, I will continue running "vmstat 1" and the endless loop of "cat /proc/meminfo", just in case I am wrong.
