How reproducible:

Steps to Reproduce:
1.install 64bit httpd package on a 64bit machine
2.create a file >2Gb in the html directory
3.try to download the file (preferably from the same or another 64bit
  machine just in case the 32bit client can't handle large files)
4.strace the httpd process to get the above output

Actual Results:  downloads fail after 2Gb

Expected Results:  complete download of files >2Gb

Can you try booting e.g. the RHEL3 kernel on this box to see if this
is a regression in 2.6?
Comment 2 Joe Orton 2004-09-09 09:54:53 EDT
I can't see that httpd is doing anything wrong here, this is either a
libc bug, or a kernel bug.


says there was a bug with these symptoms in some kernels.
Comment 3 Karsten Hopp 2004-09-09 10:18:50 EDT
Yes, looks like a kernel problem. Booting the same system with the 
RHEL3-U3 kernel fixed it for me. 
Comment 4 Karsten Hopp 2004-09-14 08:44:12 EDT
I didn't see patch for this, probably hidden in the bk-patch. But 
this works with kernel-2.6.8-1.567smp
