    Hi,


    As the SRX is currently not being utilised, other than ISIS traffic and UDP 1812, 1813 and 1814 authentication process, I am a little concerned that the J-Web "resource utilization" shows at 100% stating that Kernel = 62%, users=28% and interrupt 10%.


    When I utilise the shell and complete a "top" command, the process I can see utilisng anything above 10% is ppmd. I don't know exactly what is casuing the J-Web to show utilisation at 100% when the CPU is not doing anything?

    This has been resolved.

     

    Thankfully this is just a lab enironment until 2 weeks time when it will be installed in data centres..... 

     

    I simply rebooted the SRX to see if it would clear the issue and it has. However, this cannot be completed in a live environment.
