If so, then this bodes quite well actually. >From the previous reply in which the cred reading was extremely high it looks like the build date was just prior to the commit: FreeBSD host.dmv.com 5.2.1-RC2 FreeBSD 5.2.1-RC2 #0: Thu Feb 19 11:19:04 EST 2004 I will update the other machines in this cluster immediately to 5.2.1-Release (cvsup'ing with a release tag of RELENG_5_2 should suffice, yes?) if they are not already. Since these machines are heavy in tcp connections and run under various users (defang, mailnull, etc) your explanation makes absolute sense in light of the repaired leak. I hope this does the trick :-) Sven
