3 folders -- notice the long "flatline" at 100%
Back to my sales job on using Cacti... Had a minor issue today and it turned out that three folders had a long wait to upload results and get a new WU.

I first noticed a problem today after seeing the 'flatline' on 3 graphs mid-afternoon. So I remotely logged in, attached to the screen, and quickly discovered the dreaded "assigned to (0.0.0.0)" on the screen terminal:

[02:36:37] - Error: Attempt #9 to get work failed, and no other work to do.
Waiting before retry.

In all seriousness Cacti is a real timesaver. After I discovered and attached to the remote screen I killed FAH and then restarted to see "assigned 0.0.0.0" message again which usually means the Assignment Servers are temporarily down. Just a few minutes ago I checked the Cacti graphs and was glad to see new WUs for the 3 servers (notice flatline at 100% followed by 0% which signifies the beginning of a new WU).
