Description of problem:

Packages: ftp://ftp.linux.ncsu.edu/pub/contrib/jjneely/

From the 1.2.2 ChangeLog:

"Fix nasty issue resulting in listener instability under extreme load
(root cause was re-entering malloc/free)."

Version-Release number of selected component (if applicable):
vsftpd-1.2.0-4

Needs high disconnect/connect load.  This appeared on
ftp.linux.ncsu.edu which is NCSU's Red Hat Linux/Fedora mirror.
