    Hi Dan,

     

    You can refer to below link about jsd process..

     

    https://www.juniper.net/documentation/en_US/junos/topics/concept/jet-jsd-overview.html

     

    If you are not using any jsd, you can disable that

     

    set system processes jsd disable 

    Also we have a know issue reported in some junos releases where jsd process will be running high, you can refer to https://prsearch.juniper.net/PR1398398 for fix..

    Hello ndanl,

     

    jsd is Juniper Extension Toolkit (JET) service process, and if you're not using JET or Junos Telemetry Interface (JTI), these processes can be disabled. Please see https://www.juniper.net/documentation/en_US/junos/topics/concept/jet-jsd-overview.html for more details.

     

    It's also possible that you're hitting a known SW bug https://prsearch.juniper.net/PR1398398

     

    This is the suggested workaround if JSD and Telemetry are not required on the MX in question:

    set system processes na-grpc-server disable   
    set system processes jsd disable

    Best regards,

    Sergii
