/proc/<PID>/numa_maps is checked with the following code.

            if (f.is_open()) {

                char line[100]; //we only need the first line

                f.getline(line, sizeof(line));

                if (f.fail()) {

                    warning() << "failed to read from /proc/self/numa_maps: "

                              << errnoWithDescription() << startupWarningsLog;

                    warned = true;

so the expectation is that the first line of /proc/<PID>/numa_maps is 100 or fewer characters.

But this warning was still triggered for the 98 character first line of a numa_maps file.
