[rancid] Rancid and Nortel 8600

[Alan McKinnon]

Hi AJ,

That would explain it.

It's most unusual that it happens when brancid is running though, as
it's not idle, it's running commands in rapid succession. Tuning back
the timeout settings on the switch will probably solve your issue as
everything else you mention looks fine.

For troubleshooting things like this, I find

brancid -d <hostname>

very useful. It dumps the entire *login command to the console where you
can copy-paste it and run it repeatedly, plus lots of error output.

At this point you need to apply regular network troubleshooting techniques as the root cause is usually nothing to do with the rancid code. The "End of run not found" error at this point is not worth looking at further, it means the same as "something went wrong".
