Your IP address is making an unusually high number of simultaneous connections to the server. After a short time, try a refresh/reload on this page.

Thats what i get when i try to post or edit one of my post "BUT" that not the case on every post i make. Yesterday i made a post and wanted to edit it but i couldn't because of the error, the strange thing is i could still post a new posting.

The forum is getting more and more unusable to me because i allready have a problem with having to check "Log Me In Each Visit Automatically" when i log in else i get logged of when posting and my post is made as Guest. (Note i am not the onlyone with the loginproblem. There are other topics about this.)


Edit: At the time of writing this it will not let me post in this topic: http://www.autohotkey.com/forum/posting.php?mode=reply&t=19773

I may not be able to post in the Ask For Help Forum at all but dont want to spam it to try it out.

I also experienced it yesterday. Only closing and restarting the browser, firefox, seemed to cure the symptom.

Good to hear u are using FF which rules out that this is an browser-problem. Opera 9.2 here!

Other poeple that experienced the login problem have used FF too so again a sign that something is wrong at the serverside.

Edit: just restarted my browserwith no luck. I will not let me post in the topic mentioned above.

Do you use browser extensions such as Fasterfox which use piplineing and other prefetching techniques? If so you may need to turn them off.

No, I don't use fasterfox. I just checked my settings on pipelining and prefetch and all are set to false.
Anyway, I experienced it only once, yesterday, and interesting thing was I happened to receive the notification of the arrival of a new PM from the forum to my mail client, thunderbird, about the same time when I got this message.

Opera doesn't have prefetching afaik. The only thing that comes to my mind that may cause this is History Navigation Mode. But i turned it of and the problem still persists. Btw i checked if i can make a new topic in Ask For Help and i can. Further i could post on this topic but am still unable to post on this one.

To prevent overloading, the web server limits the number of connections a particular IP address can have simultaneously. The most restrictive limits are on PHP pages because they cause the highest load. This precaution has avoided denial-of-service outages on several occasions.

I checked the access log for your IP, but I don't see any explanation other than the possibility that Opera or your firewall/proxy is holding open connections for a very long time (minutes or hours). According to the log, you're the only one having this issue -- at least in the past week or so. Therefore, you might try using a different browser to access the forum (I realize this would be inconvenient).

If anyone else experiences this issue more than once, please let me know.

Out of curiosity, does that seem to cause issues for people connecting from large internal networks? It's quite possible for a company, organization, school board, library, etc... to only have one external IP where 50 or more users could be trying to access the forum at the same time from different machines. I somtimes connect from realtively large networks during the day on lunch breaks where it's quite possible that one or more of a thousand people could also be viewing pages on the forum at the same time.

Unless a large corporate uses massively AutoHotkey, it is unlikely that lot of people in the same network will use simultaneously the AutoHotkey forum...
Now, YouTube or MySpace, that's another story! Smile

It doesn't seem to be a problem because the limits are pretty generous. Most IPs never load more than one PHP page at a time, and the limit is 3 or 4 simultaneous PHP pages.

But if anyone gets the "too many connections" error more than once in a blue moon, please let me know.

If i want to post i can not, because it timeouts after ~90 seconds. Now i am very impatient and click on send multiple times and that is why i have so many connections open. So the problem is not that i make to many connections the problem is that i can not post. I managed to post on the mentioned topic but here is the hang. I could only send small amounds of characters. First "asd", then edited in a couple of sentences and finally edited the whole thing.

I don't know what to say. I spent many hours getting the web server set up with this protection to minimize downtime. I don't want to give that up.

No Chris the protection is not the problem. It was completely my fault that it triggered. Just keep focus on the new featureset . Wink
