IIS - AppPool StartMode changing by itself

On my developer machine, amongst my 10 websites and their respective application pools, three of them are very frequently getting setted to startMode = Always running.
I have to reset them to OnDemand regularly and I cannot find the root cause of this.
Apps are coded in C# using .Net5 and hosted on IIS 10
Below is an exemple log from the Event Logs showing the change

How to analyse a windows service dump

Im in trouble.
I have made a windowsservice that connect to differenct webservices.
In this process data is collected and saved in our MSSQL database.
Now when my service has been running for about 8-10 hours, then it suddently dumps due to System.OutOfMemoryException Stack.
How am I able/supposed to analyse what goes wrong?
I hope that one or more of you clever guys, can help me - because Im stuck with a unhappy boss :-( .
If you think - or know how - that I can deliver more relevant information, then please let me know.

Invalid SOAP Fault Start element faultcode from namespace expected

I am accessing a third party Web based API Travelport. It was working fine on pre-production credentials and URL until we decided to go to production. First i had this charset=ISO-8859-1 issue which is solved by the help of Connecting to a PHP Web service with WCF in C# But now i am getting this exception
Server returned an invalid SOAP Fault. Please see InnerException for more details.

Still not able to get the exact error
As i mentioned above, after applying the solution i am still not getting the proper error so that i can rectify it.

Azure worker role trace to development storage

I am having a lot of difficulty getting trace logs in an Azure WorkerRole written to local development storage (with the ultimate goal being Azure storage once deployed). I have googled for days and keep finding plenty of examples like this http://forums.asp.net/t/2041817.aspx?Azure+Getting+Trace+Data+to+Azure+Storage. Unfortunately, even though that discussion is as recent as March of 2015, it still references a solution that is apparently not supported. The code line
DiagnosticMonitorConfiguration diagnosticConfiguration = DiagnosticMonitor.GetDefaultInitialConfiguration();
uses the DiagnosticMonitor class which is apparently now deprecated. I am either not googling the correct things, or there is a startling lack of information on how to configure trace logs in the "newest" supportable fashion. I can find plenty of information on the old "deprecated" way.
Here is what I have so far. The app.config for my worker role has this section defined:
<system.diagnostics>
<trace>
<listeners>
<add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=2.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics">
<filter type="" />
</add>
</listeners>
</trace>
</system.diagnostics>
In fact, that was automatically added by the template that created the WorkerRole. I didn't manually do anything with that section.
The WorkerRole section in ServiceConfiguration.csdef looks like this:
<WorkerRole name="Processor" vmsize="Small">
<ConfigurationSettings>
<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" />
</ConfigurationSettings>
</WorkerRole>
And the related Role section in ServiceConfiguration.Local.cscfg looks like this:
<Role name="Processor">
<Instances count="1" />
<ConfigurationSettings>
<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" />
</ConfigurationSettings>
</Role>
Then I have a Trace statement in one of the classes in my WorkerRole project that looks like this:
Trace.TraceInformation("Handling event");
The diagnostics.wadcfgx associated with the WorkerRole in the cloud project looks like this:

Azure storage and compute emulator are successfully started when I run the application in Visual Studio. With all of that, I would expect to go to Server Explorer in Visual Studio, expand the Azure node all the way down to Storage. Go to the (Development) node and see that there is a table under the Tables node containing my trace logs, but there is nothing there.
Clearly I am doing something wrong and have yet to find documentation clear enough, either blog or Microsoft, that explains how to get this working. So here I am asking what would seem to be something relatively simple.

You're using SDK Version 2.5/2.5.1 and it does not support diagnostics in emulator. Please see this link for breaking changes: https://msdn.microsoft.com/en-us/library/azure/dn873976.aspx#BKMK_breaking. From this link:
Diagnostics logs are not collected in the Azure compute emulator – For
projects that target the Azure SDK version 2.5, the Azure compute
emulator no longer supports the collection of diagnostics logs,
including performance counters, infrastructure logs, IIS logs, and
event logs. In addition, logs are no longer stored in Azure storage or
development storage. You can continue to view application logs in the
Visual Studio Output window or the compute emulator. This only affects
projects that target Azure SDK version 2.5; projects that continue to
target Azure SDK 2.4 are not affected.
So, as of today your options are:
Target your project to use SDK Version 2.4.
Do your testing in cloud only.
Wait for next SDK version hoping that this issue will be fixed there.

Web Role - Implementing In-Role Caching crashes application (Local + Production)

I am working on a website project (converted to Web Role) to use In-Role Windows Azure Caching. Everything is working flawlessly, but the moment I enable caching, the application crashes with apparent no useful message in either IIS logs or Event Viewer. All I get is -
Event code: 3005
Event message: An unhandled exception has occurred.
Event time: 21/09/2013 23:59:39

I already have Windows Azure SDK 2.1 and also Windows Azure Caching 2.1 versions. I tried solution suggested here to no avail -
http://blogs.msdn.com/b/cie/archive/2013/08/08/windows-azure-caching-2-1-0-0-no-such-host-is-known.aspx
I have got 2 instances of web role with following settings in service configuration -
<Setting name="Microsoft.WindowsAzure.Plugins.Caching.ClientDiagnosticLevel" value="4" />
<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" />
<Setting name="Microsoft.WindowsAzure.Plugins.Caching.NamedCaches" value="{"caches":[{"name":"default","policy":{"eviction":{"type":0},"expiration":{"defaultTTL":10,"isExpirable":true,"type":1},"serverNotification":{"isEnabled":false}},"secondaries":0}]}" />

and following entries in web.config of web role
<sessionState mode="Custom" customProvider="defaultProvider" cookieless="UseCookies">

If I try to run the application with Azure Emulator, I get another error:
A process serving application pool '5e45b35f-ccd3-485e-8f12-b70178ffd1a3' terminated unexpectedly. The process id was '11096'. The process exit code was '0xfffffffe'.
and
{0} failed to refresh lookup table, exception: {Microsoft.Fabric.Common.OperationCompletedException: Operation completed with an exception ---> Microsoft.Fabric.Federation.RoutingException: The target node explicitly aborted the operation

Any help will be greatly appreciated.

I had to supply my storage account connection string instead of usedevelopmentstorage.
