I'm running a number of machines with 2.4.20 and the ReiserFS journal patches.
One problem that has started occuring is that periodically some of the machines will go really slow for a while. It's as if the CPU speed has just dropped to 1% of it's regular speed. Then after 10 minutes or so it will continue as normal. Has anyone heard of such things before? I am asking here first because the ReiserFS patch is the most significant kernel patch I've applied on what is otherwise a stock 2.4.20 kernel. Interestingly the machines that have the problems are not the most active in the file system (mail store), but the mail spool machines. The mail spool machines do a good amount of file access (but well below the limits of the hardware) and also use more memory and have large load spikes on occasion (virus and spam scanning). -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
