Technology: rabbitmq

The underlying Erlang process, Mnesia, is overloaded (` WARNING Mnesia is overloaded`).

A RabbitMQ node has entered the “memory alarm” state because the total memory used by the Erlang VM (plus allocated binaries, ETS tables,and processes) has exceeded the configured `vm_memory_high_watermark`. While the alarm is active the brokerapplies flow-control, blocking publishers and pausing most ingress activity to protect itself from running out of RAM.

The Erlang VM has reported a `busy_dist_port` condition, meaning the send buffer of a distribution port (used for inter-node traffic inside aRabbitMQ cluster) is full. When this happens the scheduler suspends the process owning the port, stalling inter-node replication, managementcalls, and any RabbitMQ process that must use that port. Throughput drops and latency rises until the buffer drains or the node is restarted.
