php file_put_contents inode problem
#if you have enough disk space(df -h) and inode space (df -i), the
#folder with lots of files, "cache" folder in this example, may be
#messed up and will likely be fixed with:
mkdir cache_new
chmod ugo+rwX cache_new
mv cache cache_old
mv cache_new cache
rsync -av cache_old cache/
