Package: apache2.2-common
Version: 2.2.9-10
Severity: grave

Debian's default mod_disk_cache config sets

        CacheDirLength 3

which creates directories like aaa ZZZ in
/var/cache/apache2/mod_disk_cache.

There are 64^3 = 262144 possible filenames. Ext3's hardlink limit is
32000. Excluding "." and "..", mod_disk_cache can create 31998
directories in /var/cache/apache2/mod_disk_cache, and will then fail
to cache more requests:

Filing as grave as ext3 is still the default filesystem type (or at
least one of), and the default apache2 config should work with it.

I'd recommend using Apache's default settings instead:

        CacheDirLength 2
        CacheDirLevels 3

Changes: 
 apache2 (2.2.22-10) unstable; urgency=low
 .
   [ Arno Töll ]
   * Fix "dbmmanage: please use Digest::SHA instead of Digest::SHA1" by changing
     perl module imports to make use Digest::SHA shipped with perl 5.10 (Closes:
     #682401)
   * Fix "Default /etc/apache2/mods-available/disk_cache.conf is incompatible
     with ext3" by changing the default to more moderate values. Some file
     systems have a hard limit for the number of subdirectories in a single
     directory. This change requires the cache directory to be purged.
     (Closes: #682840)
 .
   [ Stefan Fritsch ]
   * Add support for TLSv1.0 ans TLSv1.1 to SSLProtocol and SSLProxyProtocol
     directives. Closes: #682897
