Having a strange issue with some of our CCRs (1016 and 1036s), where the number of "pending" RADIUS requests increases slowly and never drops to zero, but strangely, remains at the steadily increasing value. The RADIUS client is used for PPPoE authentication of our customer CPEs, and uses a UDP ppp profile. Monitoring is done once per minute via /radius monitor.
See the two below resulting graphs - purple line is "pending" requests:
This one shows a lot less, in comparison:
Something strange has been going on for ages in the Mikrotik RADIUS client, and for some reason, it receives no love from the developers. RADIUS statistics in WebFig have shown zero for months now, and not been fixed.
Any ideas as to what could be happening? All these run 6.44.3 currently.
