Here is another example of Start/Stop Accounting Records. I wanted to
include pairs that work fine, then pairs of Start/Stop that "hang":

=============================
Start Stop records that works fine on 3Com TCM...

=============================

They both look the same on this 3Com??? Why is the user getting stuck? Any
ideas?

===============================
Here are Start/Stop pairs from a Cisco 2511 where the connection gets
"stuck":

Gosh, I don't see anything wrong with this, why is the user getting stuck on
the port?

Thanks,
