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

Remove the trailing slash and try again. As you can see from the error
messages, it is adding a slash itself, so it is superfluous and will
fail on most systems.

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

Or is the @ a common character on all failures?
- It need escaping on a manual move ...-

No, the filenames and directories have a variety of character
patterns:

[Thu Oct 18 09:58:18 2007] [error] (2)No such file or directory:
disk_cache: rename tempfile to hdrsfile failed: /usr/local/apache6/
cache/aptmpXskfeU -> /usr/local/apache6/cache/kR2/MPl/IuD/AUo/zNI/
cLxYQ3w.header
[Thu Oct 18 09:58:19 2007] [error] (2)No such file or directory:
disk_cache: rename tempfile to hdrsfile failed: /usr/local/apache6/
cache/aptmpNZqtzp -> /usr/local/apache6/cache/fDV/5Qr/uxb/qfB/JWT/
Et2W_Yw.header
[Thu Oct 18 09:58:20 2007] [error] (2)No such file or directory:
disk_cache: rename tempfile to hdrsfile failed: /usr/local/apache6/
cache/aptmpoDMVOF -> /usr/local/apache6/cache/oBr/zRa/Ns2/OjD/Lth/
uOfqxow.header

It looks like the top-level directory within the cache directory
doesn't exist:

stat /usr/local/apache6/cache/kR2
stat: cannot stat `/usr/local/apache6/cache/kR2': No such file or
directory

I changed CacheDirLength 3 to CacheDirLength 2 and haven't received
the error in days. It must have been a file system issue with the
number of subdirectories in the 1st level of the cache directory.
