Server crashes

[DJ-Daz]

i've removed all redundant forum themes, wp-themes, even the old phpbb folder along with wordpress plugins that aren't used any more.

Think this is being targeted for a brute force of some sort attempting to login.

I have added a plugin to lockdown the Login page, 3 attempts Max is all you get before having your IP banned.
See if this has any impact.

Let me know, if not ill putin some other steps to prevent this file, i suspect the page also gets indexed.
So will add some exclusions in etc.

[theENIGMATRON]

Also disabled the Related Post Plugin you have added.
There all common for calling the admin-ajax.php file

Sy can you limit execution time for php scripts? Make them auto killed if more than. Should stop memory hogging.

The thing is i don't know how or what plug ins are attached to other things, so i'd rather mess-hall sort it out.
I would just delete the file my end otherwise.

So lets see if anything dave has done now stops the excessive process.

@KK yeah i can and have but it still is doing it.

@KK yeah i can and have but it still is doing it but i have also enabled something else which has to be applied server wide, this will hopefully fix the issue - i hope?

the server is slow as fuck today. it was down few times but now it just takes ages to get a page. something is using resources like crazy.

[DJ-Daz]

I've gone even further and disabled even more plugins.
Also some minor changes to the layout too.

[Killzone_Kid]

Its ok now but sy should check logs around the time of my previous posts

yep i am out of knowledge on the problem, i have got the datacenter to look into it, i know that a process is being used up on mess-hall - i have restricted the script from using all the memory and it still wants to eat my resources.

It's not just mess-hall though, it's emails going mental aswell across the server, there currently is NO infections on the server, so something is wrong elsewhere so i have had to cave in and hand the problem over to the datacenter, they will get back to me on it.

So far we know whatever it is floods the server with http requests and from local files and makes the server think it's being attacked because ip's and processes are excessive.
Server shuts itself down for protection, which is not what we want.

My initial thoughts is over 10,000 concurrent connections and it will go down, whatever it is doing this is and might be the cause of it, but of course 10,000 connections to server is not normal.

[DJ-Daz]

The Dayz forum had SMTP enabled with no details in the boxes, so that might be where emails are getting held up. I've changed that back to internal.

I'm not sure where the emails are held on the system, local file or DB.

Maybe just maybe it's just this that's causing the problem?

[Symonator]

For the emails maybe, but the server going down probably not, these problems are always a thorn in my side, unless you can monitor the server 24/7 it's hard to look, logs show some stuff but not enough to warrent server downtime.

I'll find the router cause soon, or the datacenter will.
