From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8) Gecko/20060103 Fedora/1.5-4 Firefox/1.5 Description of problem: One of the defining features of httpd 2.2 is supposed to be large file support for 32bit systems. Yet it doesn't seem to work. I tried using wget-1.10.2-3.1 and firefox-1.5-4 to download a 3.1gb dvd iso file via httpd-2.2.0-4. The file does show up in a directory index, but the size comes out zero. This is on a x86_64 system with a dual core processor. [root@proton ~]# wget http://localhost/FC5-test2-x86_64-DVD.iso --00:42:34-- http://localhost/FC5-test2-x86_64-DVD.iso => `FC5-test2-x86_64-DVD.iso' Resolving localhost... 127.0.0.1 Connecting to localhost|127.0.0.1|:80... connected.

Works fine for me on a variety of systems. What platform is the system running httpd, x86 (you only mention x86_64)? Tried curl? Can you run: strace -o /tmp/httpd.t wget ... and attach the httpd.t. Anything in the server error_log?
I am testing this on a Fedora Core 5 Test 2 x86_64 system and connecting to localhost. I tried curl and got the error below. [root@proton ~]# curl http://localhost/test/FC5-test2-x86_64-DVD.iso curl: (18) transfer closed with 3235653632 bytes remaining to read I tried wget again with strace. I will attach the log. I assumed wget would work in that one of the features of a wget version a while back was that it finally supported large files.
Created attachment 123243 [details] strace log of wget
wget and curl on a Fedora Core 4 i386 and x86_64 systems get the same results.
It looks like the server is crashing. Please look at /var/log/httpd/error_log; if a segmentation fault is listed, please run as root: echo CoreDumpDirectory /tmp > /etc/httpd/conf.d/core.conf service httpd restart yum install httpd-debuginfo apr-debuginfo apr-util-debuginfo # <... trigger the crash... > gdb /usr/sbin/httpd /tmp/core.* ... (gdb) backtrace full and attach the output of gdb.
I figured out the problem. Another round of fun in SELinux world. I had disabled SELinux via firstboot to avoid such problems, but I hadn't rebooted. So I guess it automatically boots with SELinux the first time, and then respects your decesion. I simply rebooted and tried again, and now it works. Too bad the anaconda developers probably can't be talked into putting the selinux and firewall control back in the anaconda. I am sure more bugs like this are going to crop up.
Thanks for tracking this down.
