Looping cp, mv, or ftp >50 locks cgi script return to client browser

           Summary: Looping cp, mv, or ftp >50 locks cgi script return to
                    client browser
           Product: Apache httpd-2.0
           Version: 2.0.49
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: All
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: john.fauerbach@noaa.gov


This problem is in Redhat 8.0, Enterprise 3, and the latest httpd (2.0.49)
source code download from apache.org and compiled.  It is also reproducible in
perl.  This script works fine from the command line or under Apache 1.3.x.  You
can substitute different commands for the cp.  I first found it under while
trying to ftp several, > 100 files, then I shortened the code and reproduced it
using cp and mv.  The original problem was when I built a ftp command file
containing all the files to transfer and then it errored at > 50 files.

Steps to Reproduce in Apache 2.0.49 under RH 8.0 and enterprise 3 that does not
exist in Apache 1.3.x under RH 8.0, RH 7.3.  Below is the script to reproduce it:

john.cgi:

#!/bin/bash
echo "Content-type: text/html"
echo ""

var0=0

while [ "$var0" -lt 200 ]
do
echo "$var0 "
cp /tmp/hh /tmp/hI have found a reproducible bug in Apache 2.0.49 under linux
