Server too busy?

[RavenChild]

is it just me or has the server been giving messages like "server too busy, please try again later". i hope this is only temporary, or is someone hosting a dos against the site?

The server says that when too many people are trying to access to prevent overloads.

Now I don't know *exactly* how MB81 setted it, though there is some kind of blocker.

No DDOS then, rest assured.

Noticed it today too for a few minutes. It appears instead of any page of the forum, be it main index, forum index, post a reply, ....

When it happens the next time (hopefully never ) I will make a screenshot

As JAF already mentioned, if you get that "Server Busy" message,
the server is REALLY, REALLY, REALLY BUSY.

It's just showing that to prevent it from grinding to a complete stop.

It shouldn't happen often though. Right now the load is at least 20-30x
less than it was yesterday (based on the load the server needs to
have to show the busy message).

Hmm.. you should deactive this, since this Load Times are fake (hard to explain; concerns the connection to the other server which enlarge this Script Load Time Checking..). Even with current 800 running Apache PIUs, the server went never out of memory etc... all fine.

On the other hand, if the load times would be that big, how can it be, that loading the site (for example the main site) is lighting fast...

I suggest you add an announcement to the "Server Busy" notice reading,

"And don't refresh the page every five seconds! That only makes the server busier. Come back in a few minutes."

I think you confuse "server load" with load times. The server load is the average amount of processes that are in the run queue plus the ones waiting for I/O. So basically all the processes that WANT to run, but can't.

As GDpro said the old limit was 20, and the new one is even higher.. This means that more than 20 processes want to run or wait for I/O, which means the server is close to a core meltdown :P

It happened again just before ashibaka posted his comment, but it was gone after I checked again a few minutes later. I don't think there is a need for a screenshot: You see the usual header and footer, but instead of the index/forum/whatever, you see "Animesuki Forum > vBulletin Message" and then a box with "vbulletin Message" and "The server is too busy at the moment. Please try again later.".

well... i think this is a good idea indeed. i got tat messege like 1/2hr when i was in the fanart forum... then i went back after 2min/so after... it work... so instead (i think some ppl) keep clicking refresh, it may not be as bad as the issue is seem....

Hmm... i may ask how you get this wisdom ? If so, say who you are and how you are related.. As i said, the server is fine. I deactivate the limit now. In the current situation it should be more than fast.

If not, i`m going to add another server. That is the smallest problem and amount of work for me.

+ for more info the old limit was 80; think about it...

Operational experience.

If so, say who you are and how you are related..

I already answered a similar question via PM on the old forum after I sent you a short howto on synchronizing server time

As i said, the server is fine.

I didn't plan to say there is a problem with your server. There might be an error computing the load or the forum software processing it. I just noticed you confuse load with something else and tried to explain what a high load implies (usually).

Define that please. Don`t get me wrong with this, but we are talking about complex server problems (if so). It doesn`t help then much if people make server suggestions, i have the work and in the end it was nothing...

Hmm.. don`t find; just send it me once more.

Please believe me, if i say the server is fine... (while i spend hours on this kind of issues..). If we are talking about a Server Load over 80... would it be possible that the server could do a single process ? I doubt that...

I answer with quoting myself:

If my assumptions about your servers are correct, then I know the reason for the high load and that it indeed isn't really a problem. Anyway I think we should move this discussion to PM (for various reasons) and I will write you a PM with details later.
