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: http://download.hennerich.de/memory-leak2.png (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: http://download.hennerich.de/memory-leak3.png Some output of the page_owner-sort: http://download.hennerich.de/page_owner_sorted_20050310_0000.bz2 http://download.hennerich.de/page_owner_sorted_20050310_0800.bz2 http://download.hennerich.de/page_owner_sorted_20050310_1600.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0000.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0400.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0700.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0710.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0720.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0730.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0740.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0750.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0800.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0810.bz2 http://download.hennerich.de/page_owner_sorted_20050311_0820.bz2 If you need any other information, please ask...
