Nothing. I mean without change. With default value (output_buffering =
4096) bad, with output_buffering = On working perfectly. On request I
may send screenshot of Task Manager (with-and-without directive).
Thanks.

Description:
------------
On MS Windows XP Pro (SP2) and Apache 2.0.5.4 has PHP(php5apache2.dll
module) a serious problem with value output_buffering = 4096. When I
start the web-server, then I run benchmarking programs (like siege or
ab.exe or OpenSTA) and I try to access a small script that includes
phpinfo (with 50-100 simulated user connections), I get memory load
about 10MB within !one! minute (and growing) - until the RAM (715MB) is
available. Then total crash follows after this.
After two-days testing, we found (with my team-mate) little way to
solve this problem. If we set output_buffering = On , it's working
perfectly.
