I'm having a problem with the RB532 (RouterOS 4.5) at my base station. The CPU will sometimes jump to 100% and might stay that way for a few seconds or for minutes on end.
It happens at irregular intervals as well. There was not a lot of traffic when I took this screen shot at 6:45AM this morning. Only 17 out of 57 users were logged in and only 3 were actually active. I have no scripts running and I checked the log file, but found nothing out of the ordinary.
There also appears to be a lot of unreplied established connections. Before anyone asks, we haven't had any power cuts and haven't been disconnected from the Internet in days. I actually deleted all of the unreplied established connections about 8 hours prior to this screen shot.
Does anyone know what the problem might be, or how to go about finding it?
Many thanks, Gareth
