Network Outage - Nokia microwave link flapping issue

Hello everyone,

Does anyone have experience with Nokia UBT-m MPR/Microwave(formerly Alcatel Lucent).

Here is the Design and Error Image

NOTE: This is a daisy chain network & total 16 similar network is connected to R2. All the traffic is forwarded to R1 via R2.

Issue : Link between both MPRs flaps after a certain period.Line of sight between MPRs is clear. Only thing i noticed on both MPR is clock failure alarm.

What could be the possible cause/reason and solution for this issue ?
