Hi, For apache 2.0.53, RHEL4(2.6.9-5.ELsmp), I just started up 10000 httpd processes (with StartServers 10000, MaxSpareServers 10000, MaxClients 10000 in httpd.conf), and my IA32 machine got out of memory. This machine has 32GB mem, but when I 'cat /proc/meminfo', 'LowFree' has just a few MB, while others in 'HighFree'. I tried same apache in rhel4 x86_64 version, LowFree are xxGB, HighFree is zero. My questions is, since apache has thousands of processes(not just one), why does it only burn out LowMem, with HighMem untouched. Thx.
