How many idle sessions will the FWSM hold?

If we turned off the taring down of idle session how many would it hold before the FWSM ran out of memory? I undersatnd that it is a random question but it currently begs an answer from our users who wnt us to turn it off.

Lastly, what are peoples opinions on turning that functionality off?

What do you mean by Idle session?? Is it the half open sessions??

Re: How many idle sessions will the FWSM hold?

No. I mean a session, such as SSH, that is established however no traffic is neing passed on that session. The default time out for idle sessions is 1 hour.

Meaning after an hour, if the session is not passing traffic, it will be torn down in the firewalls state table. Basically, pulling the rig out from under the connection. (Both ends still think they are connected until they try to send a packet for which they get a reset)

The default for ssh keep alives (at least in Redhat) is 2 hours.

So what I am looking for is....

How many session (not passing traffic) could the firewall hold in memory before it either ran out of memory OR started taring down old connection (even if idle timeouts are disabled).
