FreeBSD w03 4.11-RELEASE-p2 FreeBSD 4.11-RELEASE-p2 #0: Tue Apr 12 13:04:36 CEST 2005     root at w03:/shared1/rw/os/FreeBSD/i386/obj/RELENG_4_11/shared1/rw/os/FreeBSD/i386/src/RELENG_4_11/sys/i686_SP  i386

>Description:
      proftpd-1.2.10 has s bug in mod_tls that causes it to flood syslog with messages:
May 11 12:07:09 w03 proftpd
May 11 12:07:09 w03 proftpd
May 11 12:07:09 w03 in free():
May 11 12:07:09 w03 in free():
May 11 12:07:09 w03 warning: 
May 11 12:07:09 w03 warning: 
May 11 12:07:09 w03 page is already free
May 11 12:07:09 w03 page is already free

They are not of facility 'ftp' (didn't check which one) and occur after every client disconnects.
>How-To-Repeat:
      compile proftpd with mod_tls, connect and disconnect (using tls is not required to see this problem).
>Fix:
      the problem is known to FreeBSD maintainer and already fixed: http://bugs.proftpd.org/show_bug.cgi?id=2313
and this patch fixes it: http://bugs.proftpd.org/attachment.cgi?id=2190
