It can occur that a new worker set prevents apache to start, although correct configured. Possible cause: Mod_JK shared file is too small Size must be at least: Header: 84 Bytes Per Worker: 400 Bytes Extra at the end: 800 Bytes Any type worker uses the same amount of memory(400 bytes): loadBalancers and hosts Configuration: …

WARNING: MaxClients of 3000 exceeds compile time limit of 2048 servers, lowering MaxClients to 2048. To increase, please see the HARD_SERVER_LIMIT define in src/include/httpd.h. Why increase MaxClients to 2048? Apache 1.x is non-threaded, so increasing MaxClients beyond 256 usually results in lower performance; often dramatically lower performance. At a prior job I worked with a …
