  • 1.  FXPC Process Eating CPU

    Posted 11-05-2018 02:57

    Hey guys,

     

    i just buy 2x qfx 3500 and run them as Virtual Chassis. There is no Traffic load yet but i see high cpu usage from the fxpc process

    "1583 root        2 -52  -52   579M   109M umtx   0  36.7H 37.55% fxpc"
    the question is, why it used upto 50% cpu and for what works this FXPC process.

    Also i have huge Ping times upto 300ms, never seen it before at Juniper devices where is no load at all

     

    Thanks

    Can you provide the complete output "show system processes extensive | except 0.00" and show virtual-chassis? 

    VCP stable?

     

    Regards,

    Rahul

    There is a thread in the code related to the 40G interfaces where it run at 500ms which cause the CPU to run high on the QFX3500 due to its process. As a workaround, you can execute below command under the shell.

     

    start shell user root

    root@:RE:0% cprod -A fpc0 -c 'set dcbcm bcmshell "counter off"'

     

    Regards,

    Rahul

    Hi Rahul,

    Does this trick solve the issue in EX3400s as well?

    Best Regards,

    Hi Supun,

     

    You need to provide below output to understand if it's same or different. Please feel free to open new thread with below output

     

    start shell 
    vty fpc0 
    show syslog messages 
    show threads 
    show threads cpu 
    show threads verbose

    Is there a way to essentially "undo" this command, this disabled all monitoring/snmp graphing of inbound traffic on all interfaces. I tried setting "counter on" but this did not work.
