Hello 37821879,
This is expected because starting with 1.25, cgroup v2 is used and it usually leads to higher memory consumption for Java, .NET and Node.JS applications.
It will use cgroups v2 from 1.25 further, meaning that 1.26 will have the same behavior.
If you deploy Java applications with the JDK, prefer to use JDK 11.0.16 and later or JDK 15 and later, which fully support cgroup v2.
You can read more about this in the following links:
