The lack of activity on this mailing li= st had me thinking no one used it anymore. I tried setting PythonOption mod_python.mutex_locks 4=2C and the problem pe= rsisted. I then tried increasing the number of available semaphores in the = kernel from the default 10 (!) to 256=2C verified that that setting had cha= nged=2C and then tried again. The problem still persists. Furthermore=2C fo= ur files that appear to be the mutexes exist in /tmp=2C named mpmtx15570 to= mpmtx15573. Perhaps mod_python isn't using kernel semaphores? Its document= ation says that it doesn't always. And /tmp isn't out of space (no partitio= n is). Any more ideas?
