Thank you for taking the time to file a bug report. Would you be able to come up with a way for us to reproduce this bug? I understand that it must be happening in a production environment where thousands of connections are being made, but maybe we can come up with a way to reproduce it locally as well.
Does this bug happen often, or is it the first time it happened? I tried finding some similar cases on the internet, but what I found were reports of real scenarios where increasing the fd limit solved the problem. Curiously, one of the solutions was to add the LimitNOFILE directive to the systemd unit file, which is already present in your case. I'm subscribing the Ubuntu Server team to this bug so that we can follow it closely. ** Changed in: rabbitmq-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1905423 Title: Rabbit reports "file descriptor limit alarm set", does not accept connections To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/1905423/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
