[ROS 6.24] SNMP Problem

Hello friends
I’m using PRTG and SNMP service to determine of interfaces or queues .
after Upgrading CCR1016 from 6.21 to 6.24 , still PRTG with SNMP is working but about 30 time in a day PRTG sensors of CCR disconnect .

I have two CCR1016 and both devices after Upgrading have this issue .
I’ve not any problem with other routres , like : RB1100 , RB1000 , RB1100AHx2 and RB493 routres .
