Arnab Ganguly did speak thusly:Hi All,Is it possible that Apache server stops responding under heavy load, but it responds to ping? What would be the possible causes for this? Remote client is getting connection refused when it tries to connect.But when the I ping the server from the client box it shows the server is alive.Thanks -A---------------- End original message. ---------------------Yes, a machine can indeed respond to a ping (ICMP echo request) while another application is not responding.Apache can get completely bogged down by a large number of requests but the ICMP mechanism is built into the TCP/IP stack in the OS and takes very little in the way of processor or time resources to implement. As far as I know, all modern OS platforms on which Apache runs are multitasking with a preemptive scheduler which means each application gets some share of the processor time on a periodic basis. So it is entirely possible that it will continue to work while Apache is overloaded.Dragon ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Venimus, Saltavimus, Bibimus (et naribus canium capti sumus) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
