Re: Cisco ASA5585-X Crash

This sounds very "buggy".  I suggest upgrading the ASA to or higher.

Re: Cisco ASA5585-X Crash

We have two of this firewalls the other one working perfectly with the same version !!!

Re: Cisco ASA5585-X Crash

Just because one ASA is not affected by a bug doesnt mean that another ASA will not be affected.  For example, we have a client with a lot of 3650 switches and they are heavily affected by bugs, while another client with same equipment is not.  

It might be that there is a feature or configuration on the affected ASA that is triggering the bug, or it might be something else entirely.

If you want to identify if this is a bug I would suggest opening a TAC case.  But upgrading to the latest ASA software within the minor release you are running would also be a good starting point.
