Le fichier spécifié est introuvable translates to file not found.

From what I read of the source code in mod_cache_disk.c it is the part from sendfile.
The error you get is from Line 555 [1]

So I think you want to play with EnableSendfile Off [2]


Please let us know if that works for you.

I'm also experiencing this problem with httpd-2.4.34 on fedora28. It appears to happen every few minutes. I have no idea what could be causing it.

This is a joomla-3.8 host (linuxsecurity.com). I believe this started after we changed the site name from webstage to www, although it could be a coincidence.

I've tried setting EnableSendfile to off, but it hasn't helped. The document root is not on an NFS share or any of the other issues explained in the Apache docs here:
https://httpd.apache.org/docs/current/mod/core.html#enablesendfile

Code:
[Sun Feb 24 09:05:14.882412 2019] [cache_disk:error] [pid 24070:tid 140295157044992] (2)No such file or directory: [client 173.212.225.134:47834] AH00708: Cannot open data file /var/cache/httpd/HRx/pOb/xK7/mTz/tMN/ioVCrxg.header.vary/ULG/TWv/f_X/eCj/Q5X/QCqsi_Q.data


Below is my config as it relates to caching:

Code:
CacheQuickHandler off
CacheLock on
CacheLockPath /tmp/mod_cache-lock
CacheLockMaxAge 5
CacheIgnoreHeaders Set-Cookie
CacheRoot "/var/cache/httpd"
# Enable the X-Cache-Detail header
CacheDetailHeader on

CacheEnable disk "/"
CacheHeader on
CacheDefaultExpire 800
CacheMaxExpire 64000
CacheIgnoreNoLastMod On
ExpiresActive on
ExpiresDefault A300
CacheDirLevels 5
CacheDirLength 3
