Hi, guys My system is DP Xeon with 8G memory. And I'm using Apache2.2.4 (worker MPM) and TOMCAT5.5.17 which connected by mod_proxy_ajp. My configuration is simple: .... KeepAlive On MaxKeepAliveRequests 0 ThreadsPerChild 300 MaxRequestsPerChild 0 MaxMemFree 100 ProxyPass /jsp-scripts ajp://localhost:8009/jsp-scripts .... The issue is that server didn't response after several hours run. All the memory and even the swap space are exhausted. The system is busying in swapping. I found that if one jsp script keeps doing requests (keepalive) that will cause the issue. So does anyone know this issue?
