If you are able to reproduce this, please provide a debug log.  See 
http://nginx.org/en/docs/debugging_log.html for details.

Restart implies that all files in the cache become active.  Please 
make sure to wait for at least "inactive=" time after a restart.

Also, please make sure that there are no alerts in logs (notably, 
no processes crashes).  It might be also a good idea to test 
without 3rd party modules if there are any.
