    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
    10:45:33  pfex: Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    10:45:33  pfex: Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    10:45:33  fpc0 Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    10:45:33  fpc0 Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    10:45:38  pfex: Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    10:45:38  pfex: Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    10:45:38  fpc0 Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    10:45:38  fpc0 Failed to allocate 6144 DMA memory:  fp_64_bit_counter mem ptr 0x0
    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.

    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.

    The list indicates the entire Junos 20 line was released with the fix included for this PR.
