Hi,
I moved my Wiki (1.9) onto an own server (Apache2, php5, mySQL5), which unfortunately does not have tht much memory (512 MB guaranteed, up to 1 GB dynamically). For that I finetuned the Apache server processes which use appr. 40 MB each. So far, so good.
Whenever I edit an article and press 'preview' the memory of one process explodes to appr. 250 MB, and when I save the article, there's another proccess using appr. 250 MB. Especially during busy phases (up to 2.000 hits/hour) the server may run out of memery, requiring me to restart the server.
What actually happens during the preview/saving of an article, that Apache wants that much memory? Is there a way to reduce the 'memory hunger'?
Thanks, Udo
