  • Creation of RX_RING failed error 12

Hi,

I restarted our Trisul probes today after a long time and getting the following error

Sat Dec 30 17:33:11 2017.742784 FATAL FilterRXRing: setsockopt: creation of rx ring failed: 12
Sat Dec 30 17:33:11 2017.742824 FATAL Unable to configure rx ring buffer

Any idea. This is a busy server monitoring 6x1G ports each in a separate Trisul context.

    Hi,

    This means RXRING cannot allocate memory required for the ring.

    Possible Reasons

    • too many trisul contexts running on one box.
    • try reducing the size of each ring. Go to Profiles > Capture Adapter > Edit - scroll down to the RXRING and select an Ring Size (Exponent) - the default is 12 ( i.e 2 ^ 12 = 8K). If you have allocated more than that try reducing that.
