From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.3.1) Gecko/20030527 Debian/1.3.1-2 Description of problem: httpd always insists on calculating Content-Length from CGI output and ignores any Content-Length header added by the CGI script. The result of this is that it buffers all of the CGI's STDOUT _before_ sending the data to the client. This leads to httpd taking huge amounts of memory for CGI's that stream data like mp3's to the client and OOM'ing the machine. I even tried to move the "LoadModule cgi_module.." at the very end of all the modules in case some filters/other modules were causing this and no difference. Building httpd-2.0.45 from Rawhide src.rpm solves the problem. this bug makes the stanard 8.0 httpd useless for me. Version-Release number of selected component (if applicable): httpd_2.0.40-11.5 How reproducible: Always Steps to Reproduce: it's easy to reproduce, just drop the following in /var/www/cgi-bin/test.cgi: ===================================================== #!/bin/sh echo "Content-Type: audio/mpeg" # modify line below to change the number to # the exact size of your mp3 echo "Content-Length: 13136351" echo # replace the following with some large mp3 file cat /home/archives/56/2003-06-09/t1055196000.mp3 ===================================================== also removing the echo "Content-Length... " entirely should also be valid, but it still insists on calculating it. Actual Results: httpd process used 30+Mb of memory. subsequent requests do the same to other httpd's processes eventually the box OOM's. Expected Results: the memory consunption of httpd processes' should not have changed much. this is the case with Apache 2.0.45 and 1.3.x Additional info:
Confirmed with Redhat 9 too. httpd-2.0.40-21.3 jh
