How to clean up /dev/shm

L1 Bithead

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/shmtmpfs /dev/shm

 

Thanks!

@gmcwilliams,

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
