When first started, it consumes appx. 4% CPU time when I run a "cvs update" on one of my client systems (the FreeBSD cvs repo is on the server). After some days/weeks of running I have seen that same "cvs update" operation cause nfsd to use up to 65% of the CPU time. Stopping and restarting nfsd seems to fix things back to normal. This on a dual lightly loaded opteron system with 2 GB of memory and running an almost 3 month old -current: # uname -a FreeBSD rancor.immure.com 5.2-CURRENT FreeBSD 5.2-CURRENT #35: Mon May 31 10:54:57 CDT 2004 bob@amidala.immure.com:/usr/obj/stuff1/src/sys/AMIDALA amd64 Has anyone else seen this behavior? Any ideas why it's happening? What can I do to further track down the problem?
