Briefly, this error occurs when Elasticsearch is unable to access the maximum size of virtual memory due to issues with the Java Native Access (JNA) library. This could be due to insufficient permissions or incorrect configuration. To resolve this issue, you can try the following: 1) Ensure that the user running Elasticsearch has the necessary permissions to access the virtual memory. 2) Check the configuration of the JNA library and correct any errors. 3) Update or reinstall the JNA library if it’s outdated or corrupted.

Log Context
Log “unable to retrieve max size virtual memory [” + JNACLibrary.strerror(Native.getLastError()) + “]” classname is JNANatives.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
if (Constants.LINUX || Constants.MAC_OS_X) {
final JNACLibrary.Rlimit rlimit = new JNACLibrary.Rlimit();
if (JNACLibrary.getrlimit(JNACLibrary.RLIMIT_AS; rlimit) == 0) {
MAX_SIZE_VIRTUAL_MEMORY = rlimit.rlim_cur.longValue();
} else {
logger.warn("unable to retrieve max size virtual memory [" + JNACLibrary.strerror(Native.getLastError()) + "]");
}
}
}
