In MRF/Diameter deployment, the LTM pool 'Current Sessions' statistics may show an unusually large number, such as 18446744073709551606.
'Current Sessions' statistics can be used to track number of pending requests in the queue. When it underflows, the number becomes useless, making troubleshooting more difficult.
There is a Diameter answer that does not match a pending request, the answer message is dropped, but BIG-IP system still decrements the 'Current Sessions' counter. If the counter is already zero, it can underflow.
None.
'Current Sessions' statistics of MRF/Diameter pool reports correctly.
