Subject:	I can jam cygwin in 10 minutes in a 1000 instance loop- can you?
To:	cygwin AT cygwin DOT com
MIME-Version:	1.0

This relates to a bug in my copy of cygwin, which jams
when the PID goes over about 36800.  With a script,
this can easily happen in less than 10 minutes, like
during a build.

How high can your PID go before you jam cygwin?  You
will have to reboot to use cygwin after jamming it.

Please run this script until your cygwin jams, and
report the highest PID found:


#! /bin/sh
i=1  # 1 Infinite Loop   a script called   "crashme" 
while test $i != 0
do
echo "$i"
/usr/bin/ps -afl | grep PID  # header row
/usr/bin/ps -afl | grep ps   #PID value
i=`expr $i + 1`
done



Why do I care to jam cygwin?  Actually, I am
incompetent to stop it, so I would like some help in
preparing a bug report.

I have a Dell laptop running Win2000, and updated
cygwin yesterday. My related posts:

http://cygwin.com/ml/cygwin/2003-03/msg01350.html
http://cygwin.com/ml/cygwin/2003-03/msg01393.html

Here is when it crashes for me:

(You can exit from the script with ^C occasionally
when you am getting close... then run it some more.  A
rest break does not fix the problem in my
experience...)

$ ./crashme
