• Probably permission denied?
• Aren't you calling it without arguments?

Found this in my searching for an answer:

If PHP's integer type is only 32 bits on your system, filemtime() will fail on files over 2GB with the warning "stat failed". All stat()-related commands will exhibit the same behavior.

As a workaround, you can call the system's stat command to get the modification time of a file:

On FreeBSD: $mtime = exec ('stat -f %m '. escapeshellarg ($path));

On Linux: $mtime = exec ('stat -c %Y '. escapeshellarg ($path));

Late to the party however noticed from your error log that you are using Simple Cache library.

Your issue might be that the cache is create as a .cache file but the line that checks it is using a .php extension.

See:

$file_expires = file_exists(APPPATH.'cache/'.$key.'.cache') ? filectime(APPPATH.'cache/'.$key.'.php')+$this->expire_after : (time() - 10);

Should be:

$file_expires = file_exists(APPPATH.'cache/'.$key.'.cache') ? filectime(APPPATH.'cache/'.$key.'.cache')+$this->expire_after : (time() - 10);

Just incase anyone else stumbles upon this
