The Traffic Management Microkernel (TMM) process may produce a core file when the system processes some WebAccelerator requests.
Traffic disrupted while tmm restarts.
Following sequence results in tmm core: 1. Negative cache entry for a GET request is created. 2. 206 response for a partial range GET for the same document as above. 3. If-None-Match conditional HEAD request for the above document.
The fix would involve bypassing 304 Not-Modified code when we have a negative cache entry.
