beos This Multi-Processing Module is optimized for BeOS. MPM beos.c mpm_beos_module

This Multi-Processing Module (MPM) is the default for BeOS. It uses a single control process creates threads to handle requests.

Setting which addresses and ports Apache uses User Group Listen ListenBacklog SendBufferSize StartThreads MinSpareThreads MaxSpareThreads MaxClients CoreDumpDirectory MaxMemFree PidFile ScoreBoardFile MaxRequestsPerThread Limit on the number of requests that an individual thread will handle during its life MaxRequestsPerThread number MaxRequestsPerThread 0 server config

The MaxRequestsPerThread directive sets the limit on the number of requests that an individual server thread will handle. After MaxRequestsPerThread requests, the thread will die. If MaxRequestsPerThread is 0, then the thread will never expire.

Setting MaxRequestsPerThread to a non-zero limit has two beneficial effects:

it limits the amount of memory that a thread can consume by (accidental) memory leakage;
by giving threads a finite lifetime, it helps reduce the number of threads when the server load reduces.

Note:

For KeepAlive requests, only the first request is counted towards this limit. In effect, it changes the behavior to limit the number of connections per thread.
