PA-500 PAN OS 5.0.2 Firewall Self Reboot.!

L4 Transporter


Any idea if PAN OS 5.0.2 has a bug that could reboot the firewall on its own?  This has happened yesterday, when the PA-500 self rebooted (obviously lost access to everything for a good 25 mins).  First thing I did was:

1. Looked at the system logs for that specific period and there was nothing evident of why the firewall rebooted. I could only see a good gap of 15 mins with no logs; after which logging was regarding the interfaces coming up etc.

2. From the cli I used less mp-log ms.log - to find some interesting stuff (snapshot attached).  At 10:36 am when the firewall went down to 10:45 am; nothing has been logged apart from the special character.  I could not find any relevant information from any other logs. 

3. I then generated the tech support file to figure out if the crashinfo had any information, but nothing was to be found.

Any ideas?  Any other ways I can find why the firewall has rebooted on its own?

Many Thanks

5.0.2 has rebooted on me a few times, but the main issue is high CPU on the management side as well as management interface via web console timing out and resetting (fortunately, not affecting the data plane).  The reboot issue was far worse in 5.0.1 for me.  Looking forward to 5.0.3.

Hi. 5.0.3 is released, you can upgrade the device now

Thanks...have it downloaded...going to pull the trigger on this upgrade tonight.

So far so good...on 5.0.3.  Management CPU still has spikes, but not running maxed out continually.

What PAN HW PA500? I still have almost 100% MGMT CPU, has anyone done an inline upgrade to the RAM for this?

My PA-3020 is now on 5.0.3 and I am noticing that it varying between 45-75% with the device not plugged in-line.
