Or maybe you have a logrotation program that needs to give Apache a 
SIGHUP signal when it rotates the Apache logs (say, once a week).  
mmcache won't work correctly after this until the temp cache files are 
deleted and Apache is restarted.  So it very easily could be the same 
problem mentioned on this list numerous times.
