All of this for a Wordpress blog. Maximum users connected in the same time is 49. Can someone help me to optimize this Debian Lenny web server?

200MB is not a lot of memory. Do not use apache if you care about memory using. Try nginx or lighttpd + php-fastcgi or LiteSpeed.

What does httpd -l produce? Best

I have no httpd command. I use Debian Lenny 32 bit. Web server uptime is about 14 hours and memory eaten is 260840k. Maybe I can write a cronjob that restarts Apache during the night. 3-4 seconds downtime are not a problem for me, because my site average daily visitors are roughly 650. I use Apache because I have more documentation and I need mod_rewrite.

Linux always caches your stuff till it maxes out its ram, its normal. The only time you need to worry is if you start using your swap. If your swap is 0, then everything is still running fine.

apache -l or apache2 -l would do the same probably.

apache2 -l Compiled in modules: core.c mod_log_config.c mod_logio.c prefork.c http_core.c mod_so.c
