	Another tip: The search function should be disabled for guests. Spam bots use the and that can drive the CPU usage even in the height.

	I'll go ahead and post something about this symptom/fix over on YaBBForum. Yours is probably not the only forum that's been attacked this way.

	But one has to imagine this. almost two years, the contribution of age and none of the Windows user has said anything. To me it is not noticed because I rarely use Windows on the Internet. The next time I'll make it but times. Perhaps even appear a few mistakes.

	Glad you found it. (You've blocked that bad person/bot, right?)

	Thanks to Dandello and special thanks to Monni. Without pointing with the acces.log I had not found the error. Such an not a very nice person (Sorry, but there it is) has a thread with full 50000 Cyrillic characters plastered in a response that actually occupied 250,000 mark. This not re-open the "News" section under Windows. With Linux it was funny enough. Well, the thing has an end after a long time (hopefully). Google just ran to this category dead and I was ordered.

	Talking to JonB - Google actually uses a custom OS so it's unlikely it would be triggering a Win specific problem. HOWEVER, a check of your access logs might shed light on which bot(s) is triggering this.

	The timeout warning on backup is one we know about - backing up large forums in a single chunk is problematical and has been for a very long time. (What happens isn't always the backup loop itself but bots and members trying to get in while the forum is in backup mode. That can boost CPU usage through the roof as each 'ping' creates a running instance of YaBB.pl.) JonB and I have discussed this at length. The failure on 'board=News' - you may need to actually look at (in Notepad++) the News.txt file in ./Boards and the messages that belong in that board. I'm guessing there's something in there - some characters (possibly hidden), or hidden code, or something else that is creating problems. Since the problem appears to be specific to this one board, the problem must BE in this one board. (In fact, since you report that this problem has been happening for a long time, it may be in an very old message.) Edited: And the timout warning on search? - Another long known problem with large forums - YaBB just doesn't have a very efficient search engine.

	I think I've found it. The forum "News" can not seem to open Windows. This is followed by Google and other search engines runs that use a Windows system, dead. I can watch the CPU usage increases. With Linux I could open the forum without any problems.

	Hello, I have found it. The error message is always the same. Quote: /cgi-bin/yabb2/YaBB.pl?board=News I give this command in the address bar (of course, previously the domain prefix), the CPU runs dead. It was not until a restart of Apache you can stop that. However, there is yet another part of what a [warn] triggers, but I could still find no CPU overload.

Once we make the first move. How do you solve level software. A robots.txt solves the problem probably not permanent. There are search engines that do not comply.

	@ Dandello Unfortunately, the problem is not resolved by the change in response # 3. I think we can not even that has to make the server operator. Now I got something in his hand and he can not make excuses himself. http://www.checkupdown.com/status/E504_de.html

	Okay, I'll look tomorrow more accurate. I'm already too tired.

You need ssh access to the server to see the mod_security log... It should be in the same physical directory as the error log. You also need root access to edit the mod_security configurations. It is possible to disable single mod_security rule on directory-level.

HTTP error 504 is usually caused by mod_security or similar module... Apache modules have own verbose log files that list the URL and description of what rule caused the hangup. Usually the page output is too big for the module to parse and it times out.
