[rancid] Rancid not backing up some HP switches but can login to them

Okay, with the proper -d and -t flags it writes the files and from there can process some of the commands.  But it seems like the .raw file isn't beeing written consistently.  Different iterations return different results for 'write term'

Once hlogin is fed a timeout it will login just fine.  hrancid (which calls hlogin) seems to be missing a 'hit' on 'write term'.

Looking at the .raw file it seems like the section of code can't find the correct line to start, and/or the .raw file isn't grabbing the data fast enough or the switch is spitting data out faster than expect can handle it.  From 3 different .raw captures I'm getting 3 different results.   Is there a way to synchronize so expect can grab what it needs to?

Ok, that makes sense, and I looked through the expect on the second test and it looks reasonable.

What happens if you do:

<from rancid home dir>
bin/rancid -t hp -d -f /opt/rancid-3.4.99/.cloginrc x.y.121.146
