I just tested in one FreeBSD-5.4-p1 box (HP DL360 with two CPU) and it seems this simple expect
program which runs six times simultaneously crashs the box after approximately 2 hours :
#! /usr/local/bin/expect
set timeout 60
set host [lindex $argv 0]
set pass "PASSWORD"
spawn ssh root@another-server
expect {
"continue*(yes/no)" { send "yes\r" ; exp_continue }
"assword:" { send "$pass\r" }
}
expect "*# " {
send "ls\r"
}
expect "*#" {
send "exit\r"
}
puts "Done."
