Aloha, Thanks for replaying my email... well yah i dont really know whether what writen on the error_log message relevant to my problem. I've read from web article, that if the error log contain so much "write data to network" might cause the httpd server freezing / hang, and the symtomps can be weekly or even in 20 mins or something. well i got a httpd server... it have a symptoms looks like that.. first the error_log got a lot of error because file not found, it seems that google caching my web page, and its (totaly) diffrent from current structure. And i tought it wont become a problem. And then i change the LogLevel, and i found a lot of "core_output_filter" "broken pipe" and other, its a lot a mount of it. And i begin to seek whats is all about, and one of the article said that it can cause the freeze. So I begin googling and join this milis. :) When the server freezing, when i check the status.. it will apper like : "httpd dead but pid file exists"... and it should be restart before it start to run again... or i've be DDos ? So can anyone help me with this problem ?
