Hi Bazis, Thanks for your response. There is a Prometheus exporter that is polling the socket and we have a health check bash script running that polls the socket approximately 4 times every minute. I am trying to figure out how often the Prometheus exporter polls the socket although is there a recommended number in terms of polling the socket?

Sometimes running syslog-ng-ctl stats takes very long and results in similar error messages. Does anyone know why this may be the case? Do these errors cause any issues with log flows through the syslog-ng service? Do they cause issues with recording of stats?
