mod_fcgid will only route a single concurrent request to a single process it has spawned, and it has no support for externally managed servers. Use mod_fastcgi at least until mod_proxy_fcgi is ready (part of future Apache 2.4). --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
