I assume you mean 5.2.1? If so, then this bodes quite well actually.

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 :-)
