However, after du exits, the nfsd still eats lots of cpu. Don't know what happened, I will give latest RELENG_6 a shot. If that does not work, I probably goes back to 6.0-R or even 5.5-PR :( By the way, I have another nfs server (mainly for backup), running 6.1-RELEASE, does not have this behavior. When do you start to notice this problem? Since 6.1-RC or? Thanks, Rong-En Fan
