If this happens that often you may want to investigate further.
Please see http://wiki.nginx.org/Debugging for some basic
debugging hints. In this particular case, it should be helpful to
see "nginx -V" output, full configuration and a debugging log that
shows how a response was placed into the cache and how it then
resulted in the message in question.
Some basic things to consider before doing anything:
- check if you are able to reproduce the problem without 3rd party
- make sure no other programs (including other nginx instances)
try to modify files in the cache directory;
- make sure there are no hardware (or other low-level) problems on
the server in question.
