I do see a similar error when trying to send a long message (318525 characters): Dec 15 12:50:35 rabbit-to-kafka01 syslog-ng[14073]: Network error while inserting into AMQP server; driver='#anon-destination17#0', time_reopen='10' Is there a limit on the length of a message going to rabbitmq from syslog-ng?

That error message happens when rabbitmq returns an error condition. It definitely should include a more detailed error cause. Syslog-ng suspends this destination for a few seconds (controlled by time-reopen ()) And then reconnects to the amqp server. I’m seeing an error in my log indicating that messages aren’t being sent to a queue in RabbitMQ. This happens a few times a week. Here’s the error: Nov 24 13:29:28 syslog09 syslog-ng[7883]: Network error while inserting into AMQP server; time_reopen='10' I have about 1000 servers sending tcp messages through a call to /dev/tcp to port on the syslog-ng server. It seems messages aren’t sent to the queue for about 1 or 2 minutes, and then it resumes sending again without error. Could this be a network issue or something within syslog-ng that’s limiting the messages? ______________________________________________________________________________ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng FAQ: http://www.balabit.com/wiki/syslog-ng-faq ______________________________________________________________________________ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng FAQ: http://www.balabit.com/wiki/syslog-ng-faq ______________________________________________________________________________ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng FAQ: http://www.balabit.com/wiki/syslog-ng-faq ______________________________________________________________________________ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng FAQ: http://www.balabit.com/wiki/syslog-ng-faq
