Have you tried with `-XX:+AdjustStackSizeForTLS` to see how that affects it? Glibc will subtract an unknown amount of memory from your thread's stack to use for static TLS so the usable stack size will actually be slightly less than the `-Xss` value, and that amount varies between platforms. See here https://bugs.openjdk.org/browse/JDK-8227417 and here https://sourceware.org/bugzilla/show_bug.cgi?id=11787
