defunct processes on UNIX server with spawn telnet

[Mike]

I have a lot of defunct processes with my expect script.

My script looks is this:

spawn telnet $host

.... do some stuff ....

send "exit\n"
expect { eof {puts $logfile "$expect_out(buffer)\n*******************\n";
sleep 5;
wait
}
}

Does anyone see anything wrong with this?

If the exit that you are 'send'ing isn't clearly telling the
telnet session to go away, you should perhaps also use the
expect close -i spawn_id id command to force it closed.

Yep. Here's the BIG RULE for Expect:

- Every exp_spawn requires a call to exp_close *and* exp_wait.

I notice that you've got your "wait" there like you're supposed to.
However, do you really want to send "exit\n" instead of "exit\r"?
