[c-nsp] ASA 5505 stops servicing inbound connections

Is this on 8.2.x or 8.0?  I'm making an assumption that it's not a 5580-SMP.  If it is 8.2.x, you may not have enough memory, our test FW is having similar issues with 8.2.1(3).  I just ordered some "Cisco compatible" RAM (Kingston Value Select) to help out with it.

Look in the log files for the following error :
<160>Aug 01 2009 15:29:49: %ASA-0-716528: Unexpected fiber scheduler error; possible out-of-memory condition

This kills our asa's (running version 8) on a regular basis (once a month), reload is the only way to resolve this. We have a case open for this, but without any good respons from cisco yet.

"Detected interface 'outside' as the Internet interface. Host limit
applies to all other interfaces.
Current host count: 2, towards licensed host limit of: 10

Interface dmz: 2 active, 2 maximum active, 0 denied"

The connections that get dropped are hitting the outside interface.
Also, the firewall is non-responsive to remote login via SSH or ASDM
when this happens.
