Hi.
I had a simple send/expect script that shoots up the CPU usage to 100%
on Unix server.
The script looks like this:
While {1} {
expect {
a {
.
exp_continue
}
b {
.
exp_continue
}
}
}
I understand that while loop could have been avoided but somehow the
user wrote the script like this. Somebody pointed out that using send/
expect in a while loop is causing this behavior (excess CPU
utilization) but I'm not sure about the logic behind this.
Expert advice needed.

What's the question?
Someone else wrote this. You're already aware that it's not
recommended style. You want ... well, what is it that you
want? I suspect you're trying to ask for the same behavior,
but with a lower CPU load, but I don't understand what
behavior (written by a third person) you're trying to preserve.
My summary advice: don't do that; decide what you do want to
do.
