Hi, I've compiled Apache2.2.14, 20 and 22 versions on Solaris10 x86 server with below configuration options. When I tried to run apache with proxy loadbalancer it is throwing core dump as below. Could some one please help why I'm getting core dump error only proxy loadbalancer instances. Configure options: - ./configure --prefix=/opt/httpd-2.2.22_32bit --enable-proxy --enable-rewrite --enable-mods-shared=all --enable-cache --enable-file-cache --enable-mem-cache --enable-cgid --enable-access --enable-auth --enable-imap --enable-deflate --with-mpm=worker --with-included-apr Proxy details in httpd.conf: - LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_balancer_module modules/mod_proxy_balancer.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_ftp_module modules/mod_proxy_ftp.so LoadModule proxy_http_module modules/mod_proxy_http.so RewriteRule ^/(.*) balancer://prd-admin/$1 [P,L] <Proxy balancer://prd-admin> BalancerMember http://xxx.xxx.xxx.xxx:yyyy BalancerMember http://xxx.xxx.xxx.xxx:yyyy </Proxy> Error: - child pid 10628 exit signal Segmentation fault (11), possible coredump in /opt/httpd-2.2.22_32bit_MPM Note: - The apache instances are running in httpd.conf doesn't contain proxy loadbalancers. Many Thanks in advance for your help. Regards, Ramesh
