[Bug 61617] New: 2.4.28 occasionally serves incorrect web page when file caching is enabled

https://bz.apache.org/bugzilla/show_bug.cgi?id=61617

            Bug ID: 61617
           Summary: 2.4.28 occasionally serves incorrect web page when
                    file caching is enabled
           Product: Apache httpd-2
           Version: 2.4.27
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_cache
          Assignee: bugs@httpd.apache.org
          Reporter: nanook@eskimo.com
  Target Milestone: ---

Not sure if mod_cache or mod_cache_disk, but with the following configuration,
and it does this whether in the main section affecting everything or a
virtual_host section affecting only one domain, it occasionally serves the
wrong page.  Usually a second subsequent request will then serve the correct
page:

    CacheRoot "/var/cache/apache"
    CacheEnable disk /
    CacheDirLevels 2
    CacheDirLength 1
    CacheSocacheMaxTime 31536000
    CacheSocacheMaxSize 1048576

     Here /var/cache/apache is a tempfs file system in order to serve pages out
of RAM.  Not anywhere near exhausting the space.  Also tried memcached and had
similar problems.

This happens with both 2.4.27 and 2.4.28.

Sorry I did not see your request for additional info until now.  I have not
observed this behavior with 2.4.41 so given that this code is antique now might
as well close this bug.

Hi Robert,

can you give us more information about the request that behaves in this way and
also how to reproduce? The configuration that you added can be used in a ton of
different environments and it might be difficult to reproduce.

Thanks!
