Thank you for the info! I upgraded to 4.5 today and I'll see if it helps. I indeed found some info in the archive that looks like a sign that my problem has been fixed - http://www.freebsd.org/cgi/getmsg.cgi?fetch=491439+494044+/usr/local/www/db/text/2002/freebsd-stable/20020120.freebsd-stable Hope it really helps.
