I dont know if its one or the other, but Im leaning towards it being ROS… The Winbox connection to the routers from dude gets hung sometimes where dude cannot reconnect to the router until the router is rebooted. I can see the connection coming into the router, but no log that the user was authorized or denied access, it just fails to connect. The only way to get it to reconnect again is to reboot the router.
Any ideas?
