I've been having an intermittent problem on my PIX 515 firewall over the past 6 months. Every once in a while the PIX will just crash. No packets are sent to/from the interfaces. I can't telnet into the unit to see if anything is going on. I can't even use a standard console cable to get to a prompt. All the lights are on, some are blinking, but the PIX is dead in the water. The only thing that fixes it is turning it off then on again.
Because it's so random, I haven't been able to figure out how or why it crashes. It can happen in the morning, night, weekday, weekend, you name it. Is there any type of logging on the PIX I can check or enable to see what type of problems are occuring up to the point where it crashes?
If you need the config let me know. Our PIX is running 6.3(1) and has 6 interfaces (3 being used for DMZ access).
Any help would be great...
