Shaun,

Usually setting PATH correctly is enough, but I don't think that is your

problem. To check that I understand the problem correctly:

All your devices work correctly except BIGIP 12. Even BIGIP 11 works

properly. BIGIP 12 fails from a cronjob but works correctly from the

command line as rancid user. This then excludes mistakes in router.db

Correct?  Yes but only with using the TERM=vt100-w for BIGIP 11.6 in f5rancid

Seems TERM=vt100-w not working in 12.0 even though the diff spits out the following in 11.6 it still works

  #

+ #Warning, can't fully initialize terminal, TERM is set to "vt100-w", status (0)

This is the case for 11 and 12 of BIGIP

What is important to note is that when the cluster is in SYNC meaning the prompt is shorter and rancid runs against the cluster --- no issues and no missed cmd(s) in the log !

Nothing in cron or the environment strikes me as being unique to the

BIGIP 12. For completeness, what is in the rancid user's environment in

a regular login shell?

If that doesn't reveal anything useful, I'd generate .raw files for both

device types and compare them. Then read those files directly into

rancid; at some point a difference in behaviour must show up
