Last night, 8 Click to start. The website is indirectly inaccessible ,ping The server , Normal network , At this time, I found iis The largest website cannot be accessed after it appears , Then iis All large and small websites on the website are inaccessible , The first payment request is IIS Fake death ……

My solution ：

1. First create an application pool --- The working procedure will be recycled （ minute ） Set it smaller , What I set up is 500

2. Right click the largest website ---- attribute ---- Home directory ------ Application pool （ Click the newly created application pool ）--- Sure you can.

3. here IIS All websites on are back to normal

The problem ： There are too many websites hanging under the current application pool , Lead to When there's a lot of traffic CPU elevated , Once it reaches a certain level ,IIS There will be fake death , At the moment IIS All websites on cannot be accessed

Found some IIS Fake death information for your reference ：

IIS Reasons for pretending to die ：

open IIS You will see the application pool , By default, there is only one application pool , View the properties of the application pool , You will find his recycling time , Default up to ,1740 minute , That is to say , Need to be in 1740 Minutes before recycling this application pool , If at this time , The requested maximum limit has been reached , Then there will be ASP The condition of feigning death , This is the fake death of large websites , Instead, , This is not the case with small websites , Because he asked less , Low flow , The limit has not been reached . Of course, it depends on the number of websites on your server .

Here's the solution :

Information 1

Single site solution :

Reduce application pool recycle time to 300-600 minute , During the recovery process , It takes a little CPU resources , Can't , For stability , Set the recovery time to early morning 5 spot .

Multi site solution ：

My server is currently down 70 About websites , I create six new application pools , Reduce the recovery time of each pool to 300 minute , Then allocate each pool 10 About websites ( This allocation is based on the number of visits to your website ) If a website , Large amount of visits , Just give him a separate program pool , But the consequence of this is that you need a lot of memory , A pool now occupies me 120M About memory , Anyway, the memory is large , No problem ,

How do so many websites allocate application pools , open IIS-- View the website properties you want to assign ,, View home directory -- You will see the application pool below , Just assign one .
