    Prior to 10.2 there was a bug in Spectrum with the code that was reading the Juniper Chassis information.  This would cause duplicate modules to be created which ultimately caused performance issues.  This was written up in technical document tec1666174 and has been updated with steps for removing the duplicate modules:

    Juniper routers chassis reconfiguration (reconfiguring) causing SpectroSERVER cpu problems and duplicate chassis modules in CA Spectrum 10.1.x and 10.2

     

     

    Prior to upgrading to 10.2 please make sure you do not have thousands of duplicate JuniperSlot modules by following the updated process outlined in the technical document.  Failure to do so may lead to performance problems when starting the SpectroSERVER. 

     

    If you aren't sure if this affects you, just log into each SS, and in CLI output the JuniperSlot modules.  If you have duplicates with the same exact name, this problem affects you.

     

    ie:

     

    cd $SPECROOT/vnmsh

    ./connect

    ./export CLIMNAMEWIDTH=50

    ./show models mth=0x3b10033 > JuniperSlotmodules.OUT

     

    Review the JuniperSlotmodules.OUT file for hundreds/thousands of duplicates and if there are duplicates, please follow the process outlined in the technical document above.

     

    Please let us know if you have any questions.

    Cheers!
