  • 1.  Error Message Mcast task out of heap memory

    I get this message repeated when trying to login to the MLX32:

    Mcast task out of heap memoryOct 27 21:12:47.740 Error:send_timeout_ind: itc_send_request() to app ITC_APP_RTM6(0x22), msg_type 0x00140002 failed ret ITC_ERR_DEST_QUEUE_FULL(8)

    Any clue as to the cause and how to resolve?

    Thanks

    It's complaining that it can't send a multicast address to the IPv6 Route Traffic Manager. Do you have tons of next-hops or neighborhood cache activities for IPv6 by chance?


    itc show error list
    itc show queue 22
    show ipv6 rtm multicast
    show ipv6 route summary
    show ipv6 neighbor
    show cam-partition usage
    show version

    Also debugging (if you want):
    debug ipv6 rtm general
    debug ipv6 rtm error
    debug destination ssh $SESSION_ID -> show who
    Later
    no debug ipv6 rtm general
    no debug ipv6 rtm error

    We are not using IPv6 in our network and definitely not on this device.

    Oh well, this does not mean that IPv6 is deactivated.
    Do you use VPLS?

    In doubt, maybe open an official support request and attach it.

    I am also sorry, but you are working for the same company or on the same MLX like the thread starter?

    What is the command to disable IPv6 on the MLX32?

    Depending on your Management and interface cards, you could switch the cam profile and reload the router. Please check the Management Configuration Guide for the MLX before.

    config t
    cam-partition profile ipv4
    wr mem
    reload


    However, in your case, it would be nice to know what causes this storm effect:
    show tech-support rtm6
