[rancid] clogin issue

[yann.moren at bluewin.ch]

Hi all,
I've recently installed and configured Rancid on a server and i have a really boring issue when trying to run clogin "device name".
When i try to test loging in, it may work 1 or 2 times but for a 3rd attempt i've got the following error:
rancid at srv-rancid01:/var/lib/rancid/bin$ ./clogin aog_benin_petrol
aog_benin_petrol
spawn telnet aog_benin_petrol
Trying 172.18.4.136...

Error: EOF received

    while executing

"foreach router [lrange $argv $i end] {
    set router [string tolower $router]
    # attempt at platform switching.
    set platform ""
    send_user ..."
    (file "./clogin" line 758)
It is sending the enable command before sending the username and password. Or maybe was it already sent but not received by the device. I tried to deactivate autoenable but no improvement.
I have to say i'm lost. I tried to look into expect and use different package version as well as with Rancid with always the same result. The parsing seems not to work correctly. Could it be related to the latency? A majority of devices from which i want to get the configuration are over satellite links.
Thanking you for support.
Cheers
Yann
