Hello, I have found it. The error message is always the same.

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.

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:

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.

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.

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.

@ XTC

YaBB tut was für seine Kunden. Es gibt bestimmt noch mehrere Funktionen, welche die CPU-Auslastung des Servers hochtreiben. Jeder sollte also mal seine logs ansehen und die Auslastung kontrollieren.

Mein Beispiel sah so aus:

53|zdravstvuyte<br /><br />здравствуйте||1424842491|admin| 

siehe Bild vom Server.

Hallo heißt auf russisch zdravstvuyte

Hallo belegt also 5 bit
zdravstvuyte benötigt 12 bit

Das ist noch nichts weltbewegendes.

Wird das allerdings in kyrillischer Schrift geschrieben, sind wir beim Thema.

здравствуйте  benötigt 96 bit und jetzt sind wir beim Thema.

50.000 Zeichen, die ich freigegeben habe, belegen dann tatsächlich auf dem Server 400.000 bit. Das in einer einzigen Antwort und der Server sagt "Tschüss Baby", zumal ja noch einiges an Antworten dann drunter kommt.

Pretty sure the answer is yes. But Subs.pm  sub exit { follows it to exit. (But in a race condition it's not going to get to exit. So if there's going to be a way to catch a race condition, it will probably be in sub print_HTML_output_and_finish { )

If JonB wasn't so swamped right now I'd ask him to join in this discussion.

In theory the Cyrillic input going over the character limit is okay since the actual number of readable characters is a lot less than the number of characters that make up the html entity equivalent. However, it also means that the characters are unreadable in raw text form. It's also possible that one or more of the Cyrillic characters got mis-converted to html entities (or deliberately mis-converted) and those characters were bad stuff - like control characters.

I know that YaBBForum had one like that from years ago (and yes, I'm pretty sure it was in Cyrillic) that had to be removed. There was hidden scripting in it.

I'm almost tempted to suggest to people with older forums to run Xenu on it (Turn off Guardian first) and see what it finds and if it triggers anything. (Xenu is very aggressive in following links and WILL trigger bad stuff if it exists - that's how I found the bad post in YaBBForum.)
