背景：我在CentOS 5.3上运行lighttpd 1.4.28-1来提供静态资产.
信号：最近,它有时会变慢.我在内核日志和/ var / log / messages中遇到以下错误：
proftpd[5145]: (::ffff:xx[::ffff:xx]) - FTP session opened. proftpd[5145]: (::ffff:xx[::ffff:xx]) - Preparing to chroot to directory 'xx' EXT3-fs warning (device dm-3): ext3_dx_add_entry: Directory index full! Sep 16 15:30:34 xx last message repeated 489 times

lighttpd的文件根目录是/ data / www / lighttpd,快速计数说我最大的文件夹只包含2k文件：
find . -type d | while read d; do f=`ls -1 "$d" | wc -l`; echo $f $d; done | sort -n
期刊腐败？还有什么可能导致这个吗？
解决方法
我有一个类似的问题,经过快速研究后,我用fsck解决了这个问题,导致我发表了这篇博文：

注意：我强烈建议在执行与文件系统相关的任何操作之前备份所有数据.
