Issue #10648 got deleted

[rayate2410]

Yesterday I created an issue about a rabbitmq crash with version 3.10.7.. But now the issue got deleted, and unable to find. Is there any way to bring it back or to know why it was deleted?

[mkuratczyk]

I didn't do it, but I guess because 3.10 is out of support. We are not going to investigate, let alone fix, issues in that version. https://www.rabbitmq.com/docs/versions

[rayate2410]

Can you help find reference of any previously reported similar issue. or with what merge request it was fixed.
Is recovery possible from this error state?
This will help me with the justification to migrate to a new version of RabbitMQ.

You are asking for support with an unsupported version. Classic queues were significantly modified since 3.10, especially in 3.12, but also in 3.13. There probably wasn't a PR specific to this issue - it was a significant rewrite of the whole area. Running up to date software is basic software hygiene - there should be no need to justify that.

@rayate2410 "has reached end of life" means "has reached end of life". 3.10 is not even covered by commercial support.

[michaelklishin]

@rayate2410 the original issue was deleted after it was moved to a discussion. Our team does not use issues for questions, which is well reflected in the issue template.

Converting an issue to a discussion still pollutes the Issues section for everyone. So we delete issues that were converted, and try to respond in the discussion. Even if it is to point out that the version you are running is completely out of support.
