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: [Wed Jul 25 06:57:08 2012] [warn] (2)No such file or directory: disk_cache: rename tempfile to varyfile failed: /var/cache/apache2/mod_disk_cache/aptmpFUtpDN -> /var/cache/apache2/mod_disk_cache/7uK/AHX/cL5/XOm/1m3/ZB2rKKA.header [Wed Jul 25 06:57:08 2012] [warn] (2)No such file or directory: disk_cache: rename tempfile to varyfile failed: /var/cache/apache2/mod_disk_cache/aptmpnobY8U -> /var/cache/apache2/mod_disk_cache/57i/JSw/tHn/P_C/t0M/YNqPp_A.header [Wed Jul 25 06:57:38 2012] [warn] (2)No such file or directory: disk_cache: rename tempfile to hdrsfile failed: /var/cache/apache2/mod_disk_cache/aptmpjS4Ddb -> /var/cache/apache2/mod_disk_cache/ZjF/x2o/r7Q/Yaj/k3C/4R63WZw.header [Wed Jul 25 06:59:52 2012] [warn] (2)No such file or directory: disk_cache: rename tempfile to hdrsfile failed: /var/cache/apache2/mod_disk_cache/aptmp5GkvgP -> /var/cache/apache2/mod_disk_cache/B0H/JPO/xnj/dBX/pr0/N@a3VOg.header 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 Christoph -- cb@df7cb.de | http://www.df7cb.de/
