I just noticed a worrisome issue.
The CPU on our RB333 that is used for a small wireless hotspot is going back and forth between 10% and 100% each time it updates (i.e. from winbox → system → resources)
I’m not sure if this is an odd GUI issue or if something else could be causing the CPU to keep spiking.
The RB is not under a lot of load (i.e. it is supporting <20 users on a DSL line) and isn’t doing anything fancy (i.e. no mangle rules) + there are only ~50 connections in the tracking table now.
I just enabled CPU usage tracking so I can get some data vs time.
Update: I rebooted the RB333 (uptime of 42 days) and the CPU load is now back down to 0-4%
