Hi,
I investigated that problem a little further.
I cvsup'd yesterday, and did a fresh make world and rebooted.
FreeBSD yoda 4.4-RC FreeBSD 4.4-RC #0: Mon Sep 10 20:24:01 CEST 2001 root@yoda:/usr/obj/usr/src/sys/YODA i386
The problem does persist. I start rpc.rstatd and xsysstats. and wait a
few minutes. Lsof then shows that filedescriptor leakage,
The filedescriptors remain open even if I kill "xsysstats" so this
program can't be the culprit.

I have a ktrace output of a run, but it is rather large, so I will send
the full output only on request. The last part is:
