"Discarded event - queue overflow" messages in zenpython log

  • 1.  "Discarded event - queue overflow" messages in zenpython log

    Posted 7 days ago
    We are running Zenoss 6.2.1 (Community). Recently we started getting a lot of these messages in the zenpython service log:

    WARNING zen.zenpython: Discarded event - queue overflow: .....[text cut]

    The queue length in MetricConsumer is at 0, and the queue length in rediscollector seems low (average of 50?).

    The rabbitmq log has a lot of "shutdown_error" messages:
    SUPERVISOR REPORT==== 22-May-2020::05:01:50 ===
         Supervisor: {<0.8363.23>,rabbit_channel_sup_sup}
         Context:    shutdown_error
         Supervisor: {<0.8363.23>,rabbit_channel_sup_sup}
         Context:    shutdown_error
         Reason:     shutdown

         Reason:     shutdown
         Offender:   [{nb_children,1},
                      {name,channel_sup},
                      {name,channel_sup},
                      {mfargs,{rabbit_channel_sup,start_link,[]}},
                      {mfargs,{rabbit_channel_sup,start_link,[]}},
                      {restart_type,temporary},
                      {shutdown,infinity},
                      {restart_type,temporary},
                      {child_type,supervisor}]
                      {shutdown,infinity},
                      {child_type,supervisor}]


    This might be the root cause (or at least related to the problem).

    Any ideas?

    Thanks in advance,
