I have a number of rb751u units acting as branch routers. Every now and then a unit will start hitting flash really hard and max the CPU. This continues until the unit is rebooted. This makes it very difficult to access the unit remotely and often requires on-site staff to unplug the unit.
There are no disk using services, no proxy, no graphing stored on disk, no logging to disk, nothing. The profiler only says 'flash'.
would be nice to have a profiler with more details to identify what is actually causing the issues.
