Hi Spuluka,
Thanks for the reply.
The Junos version is 18.1R3-S6

Is the problem resolved in Junos 20.4R3-S5.4?
Thank you so much for your support,
Thuy.

Hi everyone,
I have a pair of EX4300 in VC mode that is running version 18.1R3-S6.1
Member 0 is the master.
Before the issue occurred, there were a lot of logs below:
10:45:30 pfex: CMLC: Error writing 'CM FPC status' msg to Master
10:45:30 fpc0 CMLC: Error writing 'CM FPC status' msg to Master

10:45:41 pfex: CMLC: Error writing 'CM FPC status' msg to Master
10:45:41 fpc0 CMLC: Error writing 'CM FPC status' msg to Master
After that, the routing engines were restarted with reason: Last reboot reason 0x1:power cycle/failure
The interfaces were down.
Can somebody help me with this?
Thank you.
