in our office, we shutt down and physically disconnect the PCs to prevent damage from electrical storms. lately I’ve noticed that the shutdown of nethserver take more than seven minutes. Observing the messages during shutdown, I have noticed that the longer delay elapses with the message: “Shutting down Shorewall”; It takes longer than the suspension of a virtual machine…
Is there any way to improve this?
It is associated with the following message displayed during startup?:
Starting shorewall: WARNING: Stale lockfile /var/lib/shorewall/lock from pid 12874 removed e[60G[e[0;32m OK e[0;39m]
