Larry,
this may be a language thing - English is not my native language) -
but the script I provided does show the stated behaviour -it provides
enough load in and of itself. As I said, it sometimes fails after
50 or so iterations, sometimes after 15000, but it does fail - and
the machine is running no additional load (of course, there is the
usual plethora of programs, like Firewall, Virus scanner, etc) The
script is not run in a Cygwin box, but from windows using bash
httest.bash
#!/bin/bash
declare -ix ITER;
while :; do
`let ITER=0`
mypwd=`pwd`
if test -z "$mypwd"; then
echo "Test failed, mypwd is empty"
exit 1
else
ITER=ITER+1
echo "Next iteration is $ITER"
fi
done

Can you provide a test case that reproduces the problem for you? I'm
assuming the script you sent in your previous message doesn't
reproduce
under no-load since you state as much. If you can provide such an
example
or can describe something I can try that will surely show the problem
for
you, I'll try it on my HT machine over the weekend.
