RabbitMQ Auto Reloading Certificates Without Restart

[Dhayakar Dhaya]

Hi Support Team,
1. I am currently using the rabbitMQ v3.12.12 with Erlang v25.1 in windows 10.
2. I have a set up with old SSL certificates which is running fine, but when the new ssl           certificates are uploaded the rabbitMQ is loading the new certificates automatically. But we do not want RabbitMq to reload certificates automatically. We want to configure rabbitMq to stop auto reload/refresh of certificates and to take new certificates only upon RabbitMq restart.
3. Is there any configuration setting to stop rabbitMq from auto reload of certificate changes in advanced.config or rabbitmq.conf ?
 I came across this link where we have a way to set the configuration to stop auto reload but it doesn’t seem to work --> "trust_store.refresh_interval = 30",
 provided in this link https://github.com/rabbitmq/rabbitmq-trust-store to avoid the restart of rabbitMQ when certificates are loaded.

First of all, this is a community forum so "hi support team" is really awkward. If you are paying for RabbitMQ support, please use the appropriate channels.

Yes, RabbitMQ implicitly reloads certificates when files change. This is something Erlang/OTP does, not RabbitMQ as such.

Most users are very happy it works this way, so I've never researched if it can be disabled. You need to search in Erlang's documentation.

"SSL PEM cache" is something to look for. Alternatively, just don't change the files until you restart RabbitMQ.
