http://issues.apache.org/bugzilla/show_bug.cgi?id=43703 Summary: degradation of httpd - Segmentation fault Product: Apache httpd-2 Version: 2.2.6 Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: worker AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] when we start the apache, everything works fine, but after a while (not a fixed interval or something) the processes start to die due to segfault signal. A few processes die, and the server gets into a degradation problem, which no process gets started without exiting with signal 11. - modules loaded: LoadModule authz_host_module modules/mod_authz_host.so LoadModule log_config_module modules/mod_log_config.so LoadModule headers_module modules/mod_headers.so LoadModule setenvif_module modules/mod_setenvif.so LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule proxy_balancer_module modules/mod_proxy_balancer.so LoadModule mime_module modules/mod_mime.so LoadModule status_module modules/mod_status.so LoadModule negotiation_module modules/mod_negotiation.so LoadModule dir_module modules/mod_dir.so LoadModule alias_module modules/mod_alias.so - configuration (just used to reproduce, we noted this problem in other environment): <VirtualHost loghost:80> ProxyRequests Off ProxyTimeout 8 ProxyMaxForwards 2 ProxyPreserveHost On ProxyErrorOverride On ProxyPass /server-status !
