Management cpu usage spikes

ROS 6.2, RB2011L
Profile show cpu usage spikes up to 70% by “management” process every few seconds, then drop back to 1%.
Already tried disabling SNMP, netwatch, all services (except winbox) - no changes.

ROS configuration: OSPF, BGP, policy routing, no firewall rules, no connections tracking, no bridging, no queues.

Is it a bug or misonfiguration of some kind?

P.S. On ROS 5.24 with similar configuration (+bridge) on same RB everything was OK.

I’m using v6.1 with no issues.

After few hours “management” cpu usage became normal.
Will take a look a few days, that the problem will not return.
