httpd после некоторого времени работы выгружается и больше не запускается. На удивление, никаких фиксов для этого случая в инете я не нашел, все просто сообщают что на эту ошибку можно напороться и рекомендуют как попытаться до нее не дойти, но что делать если ты уже получил ее, ответ один - куищще. Вот пример: Architectures that use an on disk ScoreBoardFile have the potential to corrupt their scoreboards. This can result in the "bind: Address already in use" (after HUP) or "long lost child came home!" (after USR1). The former is a fatal error, while the latter just causes the server to lose a scoreboard slot. So it might be advisable to use graceful restarts, with an occasional hard restart. These problems are very difficult to work around, but fortunately most architectures do not require a scoreboard file. See the ScoreBoardFile documentation for a architecture uses it.

httpd выгружается из-за того что ему недостаточно памяти, сделай своп.

З.Ы.: vsftp сервер после передачи файлов забирает всю память в кэш, как сделать чтобы она потом опять освобождалась? и надо ли это делать?

How many php CGI processes will lighttpd spawn? ¶
lighttpd has three configuration options that control how many php-cgi processes will run:

PHP_FCGI_CHILDREN (defaults to 8 before 4.3.0, 0 after; see below)
min-procs (default 4)
max-procs (default 4)
When lighttpd starts, it will launch min-procs parent php processes. Each parent process then pre-forks PHP_FCGI_CHILDREN child processes. For example, if min- and max-procs are 4 and PHP_FCGI_CHILDREN is 16, lighttpd will start 4 + 4 x 16 = 68 processes.

To disable lighttpd's process control, set min-procs and max-procs to 1 and set PHP_FCGI_CHILDREN to the number of processes you want to spawn.

In the case of lighttpd 1.4, php 4.3, and eAccelerator 0.9.3 on Linux, eAccelerator will create a separate memory space for each parent process. If you leave min- and max-procs at 4, you'll end up with four separate eAccelerator caches. However, if a php parent segfaults, you'll still have three groups available to respond to queries. For this reason, Jan recommends setting min- and max-procs to 2.

After PHP 4.3.0, PHP_FCGI_CHILDREN defaults to 0. If left at 0, PHP will not pre-fork any children, so only min-procs parents will handle requests.

PHP 5 seems to start one parent process and one child per min/max-procs and PHP_FCGI_CHILDREN defaults to 1. What I suggest is splitting the number of processes you want between min/max-procs and PHP_FCGI_CHILDREN. The number of processes spawned = min/max-procs*(PHP_FCGI_CHILDREN+1). For my setup, I have min-procs and max-procs=2 and PHP_FCGI_CHILDREN=4.

Note that setting PHP_FCGI_MAX_REQUESTS is recommended to avoid possible memory leak side-effects.
