According to the sysinfo manpage ( https://man7.org/linux/man-pages/man2/sysinfo.2.html ) the memory and swap related entries in the struct sysinfo are given as multiples of mem_unit bytes. "In the above structure, sizes of the memory and swap fields are given as multiples of mem_unit bytes."
This is considered in most parts of the OpenJDK codebase when sysinfo is used but not all; should be added where it is missing. ------------- Commit messages: - JDK-8324598 Changes: https://git.openjdk.org/jdk/pull/17550/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=17550&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8324598 Stats: 3 lines in 2 files changed: 0 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/17550.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/17550/head:pull/17550 PR: https://git.openjdk.org/jdk/pull/17550
