disk_cache: rename tempfile to hdrsfile failed ERROR

Hello,

I recently implemented disk caching on my apache server. As the
server serves content and that content is cached, the following
message becomes more and more frequent in the error log:

[error] (2)No such file or directory: disk_cache: rename tempfile to
hdrsfile failed: /usr/local/apache6/cache//aptmpvRnbm6 -> /usr/local/
apache6/cache//kxh/qau/zdc/1hF/rj@/h1qn0xA.header

to the point where they are a few dozen or so such errors per minute.
Any help resolving this would be appreciated.

Thanks,
Mitch

After updating the confige, the problem persists:

(2)No such file or directory: disk_cache: rename tempfile to hdrsfile
failed: /usr/local/apache6/cache/aptmpRTj1cY -> /usr/local/apache6/
cache/0@l/JjP/cYk/Zot/iX@/OlK0EJw.header

There are gigs of cache that have correctly saved to disk. It looks
like an intermittent problem. Could this be a file system problem
regard a maximum number of directories or files per directory?

Thanks,
Mitch
