The RabbitMQ log contains messages similar to "lager_error_logger_h dropped X messages"


You might encounter an issue in which the RabbitMQ log contains messages similar to the following:

lager_error_logger_h dropped <x> messages in the last second that exceeded the limit of <x> messages/sec

In the message above, <x> refers to the number of messages.

The RabbitMQ log is called rabbit@<hostname>.log, where <hostname> refers to the name of the machine on which RabbitMQ is running. This log is located at /var/log/sas/viya/rabbitmq-server/default.

This warning might occur even when the workload of RabbitMQ is low. In this case, the warning is incorrect and can be ignored.

The incorrect warning occurs due to the following:

The problem is described in the GitHub post, Lager incorrectly counting dropped messages from Error Logger. The problem is solved in Lager 3.7.0
