I have a directory with a large number of subdirs (XFS filesystem). When I try and browse this in a (reasonably) default apache configuration the apache thread serving the page hits 100% CPU and never generates the page. Reproducible: Always Steps to Reproduce: 1. Create directory with lots of subirs mkdir /var/www/localhost/test cd /var/www/localhost/test for i in `seq -w 1 3000` ; do mkdir $i`echo $i | md5sum | awk '{print $1}'` ; done (Don't know if the total length of text that makes up the names or simply the number is important) 2. lynx http://localhost/test/ Actual Results: Use top an and see apache thread at 100% cpu, try again from a different client and there will be another crashed thread. Expected Results: Directory listing rendered in browser. System is running Xen, happens in domU and dom0. Tried various Apache indexing options but always yields the same result.
