Hi everyone,
Been receiving alerts for a little bit around tmpfs /dev/shm being at 99% - how should we clean up this directory? What is this directory used for?
tmpfs /dev/shm
Thanks!

The workaround I have is that the Palo Alto needs to be rebooted. While we haven't run into any issues with it at 97% I would say it's safe to do a monthly reboot to clean up the directory.

Restart the firewall. /dev/shm is used on the firewall the same as it is on any other Linux system, it's a temporary file store that uses memory instead of disk like /tmp does. Outside of restarting the firewall I'm not sure there's a way exposed to actually do anything about it outside of a reload.

Does 10.0.* cause this to fill up faster?
EDIT: Is there anything we should worry about if this folder fills up? I just don't want an unexpected crash

Typically this is cleared on reboot but after upgrading to 10.0.6 its failed to clear the space on system reboot.
I have looked at the other drives on the PAN are there seems to be no capacity issues other then the tmpfs /dev/shm location at 97%.
Can yoU confirm whether this is expected on later versions 10.0.x +?

Where you able to to clean it, where you able to get to know why it is high.
