What is the reason that SNMP case high CPU - OmniTik UPA?

I have several OmniTik UPA running but on one SNMP case high CPU load 70-100%
config is almost same on every unit - all ports are in bridge no firewall no extra settings are in place.

Can it be hardware problem?

I already did system no default reset and configure unit again but no luck.
I m using 6.10
Has anyone experience same problem?

Thanks.

Hello Lakis, try with RouterOs 6.11 if it still the same.
