This signature detects a long string of "No Operation" (NOOP) commands sent in an HTTP request that has been malformed. Some vulnerability testing tools incorrectly send a NOOP sled without completing the request. This is generally a benign request that would not exploit the target. Your server is possibly being probed by a test tool.
