User-ID causing high CPU

inzamam.shahid — Fri, 22 Jul 2016 16:00:53 GMT

Hello People,

My client has receently upgraded to 7.1.3 and now the management plane is constantly running 100% on all firewalls.

This is the following message displayed and filling up the userid.log

2016-07-22 16:43:38.660 +0100 Error: pan_user_id_agent_msgs_queue_msg(pan_user_id_agent_msgs.c:58): failed to insert msg into sending msg list

We have restarted the user-id process, but that has not made a difference. Here is the output of show system resource follow:

If you could let me know how to reduce the CPU that would be great.

Thanks,

The 3020's were having some issue with this exact issue on 7.1.2 that had people downgrading earlier, however 7.1.3 was supposed to stop that from being an issue. I would contact your SE or open up a support case with it if you can but this was the same issue that was affecting earlier builds of 7.1.*.

Please keep us up to-date on this though, as our company has been talking about upgrading to 7.1.3 with the newest security vulnerabilities that came out this/last week or continuing on to 7.0.8.

Hi Guys,

Just thought I should give you an update with regards to this issue, so I logged this with TAC and after the troubleshooting it has been concluded as a bug. I believe this bug is specific to us as we had three firewalls acting as User-ID agents for themselves and other firewalls. As we were not using this feature anymore we disbaled this and it bought the management CPU down. This is being tracked in bug 100988.

If you would like anymore info please let me know.
