After upgrade from 6.42.12 to 6.48.1 i have a problem with links bandwidth graphs, only when dude server getting data via routeros protocol. SNMP works correctly. Each time i try to connect, the graph is distorted with peak x2. This issue occurs on every links graph.

I was wondering about that and was about to post myself.

For quite a while now our charts look like this attached picture with "spikes" that are not real and don't show up in "normal" bandwidth charting from the direct interface or other monitoring tools.

What is the best way to fix this??
