spring-boot version 2.6.6
this issue appear occasionally service deploy in k8s
Comment From: philwebb
It looks like another application is using one of the ports that you have configured. I don't think this is a bug in Spring Boot itself, but if you're able to provide a sample that replicates the problem we can reopen the issue and take a look.

this issue appear occasionally, I can't provide a sample, but our service deploy in k8s , Does CloudPlatform KUBERNETES have special logical ?
Comment From: wilkinsona
No, CloudPlatform.KUBERNETES should not have any effect on server.port and management.server.port.
I noticed above that you're using Spring Boot 2.6.x, open source support for which ended in November 2022. You should upgrade to Spring Boot 3.1.x or later. Alternatively, commercial support for older versions (including 2.6.x) is available.

We spend a lot of time upgrade to 2.6.x . In short term we don't have plan to upgrade to Spring Boot 3.1.x. I found when this Port xxxx is already in use occur, I enter service use netstat this port not exists, I'm confused about this issue, Do we have some direction about this issue ？
Comment From: wilkinsona
Even if you were using a supported version, we'd be unable to provide direction for a problem that we don't fully understand and cannot reproduce.
Comment From: Dr-wgy
I choose 60000 as management.server.port I found that my service use 60000 as ephemeral port to communicate with the mysql(redis,dns)
cat /proc/sys/net/ipv4/ip_local_port_range
32700 60900
So I use below 32700 port just like 30001 this issue is not exsits
Comment From: xiangtianyu
Actually, i met the same problem, i set management.server.port=${server.port} and in k8s, it start failed and report "port in used", and when i set it to management.server.port=8081, it start successfully. And even when i set to "management.server.port=8080", it still start successfully. What's the special of "management.server.port=${server.port}"?
PS: When i start my app locally, it's all ok. And in k8s env, i must set management.server.port to different port.
