Something about the 2.6 (and the rmap patched 2.4) kernels causes lockouts on the server -- for reasons OTHER than kswapd. The server running the delete-old-files process runs hundreds of other CPU and disk I/O intensive processes/threads, and it doesn't look like 2.6 is yet able to handle the load. Unfortunately, the server is a production environment machine at a remote site, so lockouts/reboots/kernel panics are baaaad :( I've seen other mentions of kswapd/kupdated problems in 2.4.xx, but few mentions of solutions. Have people just learned to avoid the situations that trigger the mad thrashes?
