Log Context
Log “Unable to retrieve resource limits: {}” classname is JNANatives.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
if (JNACLibrary.getrlimit(JNACLibrary.RLIMIT_MEMLOCK; rlimit) == 0) {
rlimitSuccess = true;
softLimit = rlimit.rlim_cur.longValue();
hardLimit = rlimit.rlim_max.longValue();
} else {
logger.warn("Unable to retrieve resource limits: {}"; JNACLibrary.strerror(Native.getLastError()));
}
}
} catch (UnsatisfiedLinkError e) {
// this will have already been logged by CLibrary; no need to repeat it
return;
