Are you sending exit to end the session Like:
exp_send -i $spawnid "exit\r"
this may not clean up the children processes you should always wait
for the eof or timeout and
if you timeout then you should kill the children then harvest the
children. Like so
set pid [spawn telnet $ipaddr ]
set sp_id $spawn_id
# do your work here
.....
# now exit
exp_send -i $sp_id "\r" ; # get the prompt again
set timeout 10
expect {
-i $sp_id
-re "$prompt" {
exp_send "exit\r"
exp_continue; # we continue because we want eof or timeout
}
timeout {
exec kill -9 $pid
exp_continue ; # optional with -9 its dead
}
eof {
;
}
}
# now cleanup harvest the child by "waiting" for it otherwise it
becomes a zombie
puts " Exit status : [ exp_wait -i $sp_id ]"
catch { exp_close -i $sp_id }
Note I just typed this in the browser so you may need to adjust...
