At one of my customers they are using a CSM and we saw that we have a lot of connections in the state CLOSING .
According to the docs it means that it is waiting for the FIN ACK .I haven 't done any sniffing to check if the fin ack arrives or not .
But you have also an idle value of 3600 sec so in my opinion the connection should close after an hour even if the FIN ACK is not arriving. And this is not the case . Has anybody seen this before and can I do something about it ?
I checked the bug toolkit but didn't find anything .
We are running v 4.2(3)
