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." > > Cheers, if that can help -- Philippe PEGON
