Relevant telegraf.conf:

[[outputs.amqp]]
brokers = [ "amqps://rabbit1:5671/", "amqps://rabbit2:5671/", "amqps://rabbit3:5671/",]
username = "foo"
password = "bar"
max_messages = 100
exchange = "telegraf"
delivery_mode = "persistent"
tls_ca = "/etc/telegraf/ssl/ca-chain.crt"
tls_key = "/etc/telegraf/ssl/telegraf-client.key"
tls_cert = "/etc/telegraf/ssl/telegraf-client.crt"

System info:

Ubuntu 16.04.5 LTS
Telegraf 1.8.2 (git: HEAD 996a91f2)

Repro steps

  1. setup 1+ rabbitmq instances
  2. configure telegraf to publish to rabbitmq
  3. set max_messages (perhaps to a low value) and wait

Expected behavior:

Whenever a new connection is established due to reaching max_messages, the old connections should be closed.

Actual behavior:

Connection amount seems to increase indefinitely, which consumes memory and sockets.
