I have a question about the concurrent connections on the FWSM.

yesterday,our FWSM is down beacues too many of concurrent connections.

so we reset the FWSM.

before that we check the number of concurrent connections is 19765160 !!!

But the capacities of the FWSM is 1 million. why ?? the concurrent connections can pile up to 20 million??

It might be inactive sessions but still shown in the show output. So, total concurrent sessions crosses the maximum capacity.
