  • 1.  dfwd log entry

    Posted 01-10-2019 10:02

    I am seeing the following log entries 2-10 times per day on my MX204 that is configured as a PPPoE BNG (that is it's only function):

     

    Jan 10 10:28:31  dnvrco-cmfl-mx204-1 dfwd[70475]: shmlog: argcnt 296 not enough memory for argtype: dfwdcc-prio-str: created with 0 mappings (needed 8096 remaining 😎
    Jan 10 10:28:56  dnvrco-cmfl-mx204-1 dfwd[70525]: shmlog: argcnt 296 not enough memory for argtype: dfwdcc-prio-str: created with 0 mappings (needed 8096 remaining 😎

     

    Are these of concern?

    Hi Sean,

     

    From your other/previous post, can I assume you're on junos 17.4R2-S1.2?

    The messages are related to engineering log used to track what is happening on the router.  It is a diagnostic tool and doesn’t impact router functionality. The amount of memory allocated for the logging facility (referred to as shmlog) is specified based on the running platform. The messages merely indicate that when some parts of the software attempted to allocate some space related to the logging facility the logging facility returned that there was no more space so that their allocation  request was denied.

    it's cosmetic in nature, shmlog functionality was not affected and doesn't impact any customer/service functionality.

    These logs are not harmful and you can filter them using KB9382.

     

    This has been fixed by PR#1384371 & PR is resolved in the following Junos versions:
    junos:16.1R4-S12 junos:16.1R8 junos:16.2R3 junos:17.1R3 junos:17.3R4 junos:17.4R3 junos:18.1R3-S1 junos:18.1R4 junos:18.2R2 junos:18.3R2 junos:18.4R1 junos:19.1R1
