Ok, we had another crash this morning after an uptime of only 36
hours 8-(.
No oom-killer this time, but we got a very high load (>40) in the
end. Our cron-job which starts the page_owner-sort every 10 minutes
didn't return the last 4 times.
The new 2.6.11-kernel changed the graphs a little bit - values for
'MemTree' are much higher, but values for 'Cached' and 'Buffered' are
still very low.
Here the graph for the last week:

(the left part is the same like our first graph last week
http://download.hennerich.de/memory-leak.png, the weekend is well visible)
Detailed view of the last 40 hours:
