Umbraco 7 slow on production server and keeps restarting

Question

Local on my laptop the umbraco projects runs perfectly, but when I put it on the production server the backend is very slow.

Specs of VPS:

Windows Server 2012
1 CPU with 2 Cores 2.2Ghz
4Gb RAM
IIS8
MSSQL Express

Umbraco version

7.4.1

Also when I add new nodes or other changes in the backend it sometimes hangs and then I see in the log that the application has restarted.

Log see below:

Anyone that has suggestions about this?

Probably need to install this patch: http://issues.umbraco.org/issue/U4-6338 Also: always make sure to specify your umbraco version, might've be a bug that's already fixed. — sebastiaan, Mar 23 '16 at 19:11
@sebastiaan thanks for the intel I will test this. Version is 7.4.1. — Mivaweb, Mar 24 '16 at 12:13
This also sometimes happens when you have corrupt indexes. I think it's the`App_Data` folder you need to delete (umbraco will rebuild it), but back it up first! — glcheetham, Mar 25 '16 at 09:05

There is a Windows Server 2012 R2 hotfix for this issue which can be found here - once installed the issue no longer occurs.

I had the same problem recently and turned of examine indexing because it forced a configurationchange.

Try this out, go to /config/ExamineSettings.config

And comment out the providers

<providers>
  <!--
  <add name="InternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true"
       analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"/>

  <add name="InternalMemberIndexer" type="UmbracoExamine.UmbracoMemberIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net"/>

    <add name="ExternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"/>
  -->
</providers>

It should stop the app pool restarting every time something is saved, but i don't know why the Indexer is forcing a refresh
