Hi,
Looking for help on why my Apache process's memory continues to grow
until it uses up all avaliable memory when using AB to make simple http static
page request. See details below but I have setup Apache to use http keep
alives and am reusing the connections.
Httpd memory reported by ps aux:
%MEM VSZ RSS
Start: apache1 74459 0.0 0.0 186156 4708 ? Sl
17:16 0:00 /home/httpbld/bin/httpd -k start -f /home/httpbld/conf/httpd.conf
AB 5min:apache1 74041 354 0.9 4511532 2445212 ? Sl 17:03 41:14
/home/httpbld/bin/httpd -k start -f /home/httpbld/conf/httpd.conf
To have the RSS memory grow to over 2GB seem excessive. Please let me know if
this is a known issues.
Thanks,
Dean...
