Pktclass Blob load failed

BIGIP version: 15.1.2.1

 

We are encountering this error on Viprion C4800; is there anyone encounter the same error from your environment?

Is this related to this bug : Bug ID 709563 ?

    Hello Troy​ 

    I'm unfortunately unable to find documentation if that bug is what is causing the specific error, however, I would still like to encourage you to update your device to a supported version. To see any bugs you may be impacted by you can use iHealth Upgrade Advisor and I would also suggest following our Software Support Policy for the most up to date supported versions. 

    Thanks for being part of our DevCentral Community!
