High CPU usage and flowd_octeon_hm crashing Juniper SRX340

  • 1.  High CPU usage and flowd_octeon_hm crashing Juniper SRX340

    Posted 05-22-2023 10:28

    Hello!
    We've got used Juniper SRX340, not new. And we have problems with it
    CLI works very slowly, CPU utilization is constantly high, none of the ports except mgmt work. 
    Log shows flowd_octeon_hm crashing
    It seems that I've got these troubles after I update junos version from 19.4R3-S1.3 to recommended 21.2R3-S3.5. Now I rolled back to 19.4R3-S1.3 and but the problem remains.
    Default config loaded and only the console cable is connected to the device.
    Any ideas? I would be grateful for any advice
