Thread:Project:Forum/MediaWiki uses too much RAM and CPU

Hi,

i have a Wiki. It works for about 2 jears just fine. It has 2500 unique/day. After 31.1 the users increased to 4700 a day.

Now the wiki uses 99% RAM (512) and so much CPU that ftp/email and other services dont work too. Visitors are ~40 at a time.

I have a good server (not a v-server). For 100€/Month.

Since i upgraded to 1.16 this error message comes when 40 users are online.

Code:

Sorry! This site is experiencing technical difficulties. Try waiting a few minutes and reloading.

(Can't contact the database server: User d008d639 already has more than 'max_user_connections' active connections (localhost))

When i am alone on the Wiki and i open the Mainpage it lasts 3-4 Seconds for the site to load. Other sites load in 0,5 secs. When 4 users are in that wiki each site takes 6 seconts to load.

Can anyone help me?

Regards 89.12.248.148
