Default Sudden increase in server load at specific times

Within 6-11 pm GMT I get high load averages on my forum, my webhost says the load comes from showthread.php and MySQL.
I have tried disabling all mods but also load is very high.
My site is on a dedicated server.
This happens between 6-11 pm GMT when online are >13k.
Any other time the load is fine and the website is working fine.

url : nmisr.com
Any help?

You need to check your statistics..etc to see who is on your site at those times, which ip's and how many connections per ip.

Lately there has been a rash of IPs hitting vbulletin sites for what ever reasons and most of them are Chinese IPs. I just helped another member here who was getting hit with tons of IPs and we blocked them through htaccess.

It is going to take a few hours of monitoring your site but you will get it under control. Here is the link to that member's thread :

https://vborg.vbsupport.ru/showthread.php?t=302628

If you need some help let me know, but it will require me to have access to your cPanel.

thanks for help CAG and Simon, but all hacking or attacks possibilities are excluded
all the 13k online are random arab visitors !

It is very normal that MySQL and showthread.php consume lots of resource.

13k online in the same time? my site have 1200-1500 user online in the same time (showing from realtime google analytics), i'm using dual e2620 with memcache + apc, and 64gb ram, raid 10 ssd. the CPU load average is around 7.00 to 10.00.

As long as the site load time still fast, i think nothing to be worry about it.

Unbelievable !
When I added the code in htaccess the load markedly decreases, but it is still high about 50 with 14k online.
so do you have any updated list for these ips to block?

Which one did you add the one from the thread I gave you?

Also use Simon's Ban Spiders by User Agent to block those bots we do not need on our forums and sites:

https://vborg.vbsupport.ru/showthrea...ht=ban+spiders

Here is the list I use, I block facebook, bing, msn, alexa and some others, why? I don't need them and they always seem not to play nice when they crawl my forums....I recommend you replace the list that comes with this mod with this one below:
