I originally thought this might be related to the SNMP bug posted by Tristram however since disabling SNMP and removing all SNMP entries on an RB800 encountering this issue it still occurs.

After testing on an RB800 running 5.2 MikroTik Support was able to replicate some issues.

I have also experienced this on RB1100 and am looking forward to a fix !

It appears to have stopped since the client stopped using Eth13, not sure if it is related, but a bit of a coincidence.

Mikrotik reports traffic-flow is causing the issue an this will be fixed in v5.6
