IIS stop responding - W3WP massive memory Usage

A very common problem in SharePoint portal is W3WP that going crazy. In some cases the memory usage is 900MB to 1GB. Obviously, in this situation the IIS on the Front-End Servers will stop responding.

Two things must be considered.
One – we need to solve the problem, taking into consideration the existing situation. And it will expand down.

Two– we need to consider whether the system hardware can deal with the amount of references to applications. This is because such problems are usually lack of resources - mainly processing capabilities (CPU) or a lack of available memory (RAM).
In such situation I recommend to re-edit the SharePoint Capacity planning…

How to fix the problem:
First we need to log on to the front end servers.
Start the IIS Console. On the portal application pool right-click the mouse and mark properties.
The properties window will open and in the Recycling tab we need to check the "Maximum used memory".




The value that I found is working for me – 500-600MB.
