ASP.NET Session - Internal ArrayList exception - asp.net

We have a web based application developed using the .NET framework 4 and ASP.NET MVC.When you set an item to a session in a section of the code, we are faced with an internal exception directly from mscorlib which causes our application to work unexpectedly.The fault stack trace is as follows;

We know that the Session is not thread-safe for some operations.When we analyzed dumps we didn't see any other thread trying to access the same session object.We checked the source code of .NET in referencesource.microsoft.com and we think that it is a related an error indexing the internal array of the ArrayList.I'm not sure, but it seems to have a memory problem.Any ideas?

Databases have "Recovery Pending" status every few hours

I recently noticed that most of the databases on my SQL Server are getting the Recovery Pending status after running for a few hours (sometimes 6, sometimes more). I can't imagine this being the expected outcome, so I decided to post about it here.
I opened the Event Log viewer and decided to find some more info about what's going on. It seems that all my databases are "Starting up" every few minutes or so (as cam be seen here). Some of them get started multiple times in a row. Is that supposed to work like that?
After scrolling a bit more, I found this warning from one of my IIS websites:

Custom event details:
Seems like there's something wrong with SignalR, so it shouldn't have any direct relation with the database, but there aren't any other errors/warnings there.
Am I missing something here?
Thank you!
Do you have "auto close" enabled on the database?
Best practice is to have it OFF
ALTER DATABASE <mydb> SET AUTO_CLOSE OFF
I would also check AUTO_SHRINK while I was there

How can I specify the ASP.NET probing path for automatic C++/CLI appdomains?

I have a C++/CLI DLL that needs to run in the context of an ASP.NET WebApi action.
The action is affected by an ActionFilter that uses log4net's LogicalThreadContext to set a property containing a request ID; this works nicely to write the request ID into the log entries.
The problem is that ASP.NET seems to be creating an appdomain when it's time to load the class from the C++/CLI dll. (I can't seem to find any documentation on how that works; I'd love to find some.) When the appdomain plumbing tries to deserialize everything, it chokes because it can't find log4net.dll (see stack trace below).
Fusion logs show that it's looking in C:\Windows\System32\inetsrv, which is incorrect... I would expect it to look in the probing path or along the %PATH% environment variable.
A few data points:
log4net.dll is available in the web app's bin directory and works fine for everything else I'm using it for.
The C++/CLI code has no dependencies on log4net.
If I comment out my calls to log4net.LogicalThreadContext.Properties[...], everything works fine.
If I copy log4net.dll from my bin folder to C:\Windows\system32\inetsrv, everything works fine.
The web.config file specifies the probing path with a <probing privatePath="bin"/> element.
My Application_Start method in global.asax.cs prepends the web app's bin directory to the %PATH% environment variable:
var currentPathEnvVar = Environment.GetEnvironmentVariable("PATH");
var binPath = Path.Combine(Server.MapPath("~") ?? String.Empty, "bin");
_log.DebugFormat("Prepending paths to PATH: [{0}]", binPath);
Environment.SetEnvironmentVariable("PATH", String.Concat(binPath, Path.PathSeparator, currentPathEnvVar));
The log shows that the %PATH% is getting prepended correctly:
2015-06-05 17:07:48,816 1 DEBUG MyNamespace.WebApiApplication (null) Prepending paths to PATH: [C:\Program Files\MyCompany\MyApp\web\bin]
So how do I get the appdomain that ASP.NET creates to look in the right place to load assemblies?
Thanks.
Here's the stack trace that gets logged when all this goes down.

This helped me to resolve similar issue:
https://blogs.msdn.microsoft.com/jorman/2007/08/31/loading-c-assemblies-in-asp-net/
Faced option 2.a and proposed solution worked fine:
protected void Application_Start(object sender, EventArgs e){
String _path = String.Concat(System.Environment.GetEnvironmentVariable("PATH"), ";",
System.AppDomain.CurrentDomain.RelativeSearchPath);
System.Environment.SetEnvironmentVariable("PATH", _path, EnvironmentVariableTarget.Process); }

What does GCFrame mean in output of !clrstack command in WinDBG?

Can somebody help me with answering my 2 questions below?
What does GCFrame mean in !clrStack output?
What does System.IndexOutOfRangeException..ctor() showing in the stack mean? Does it mean there is actually exception on thread?

The exception is in the process of being constructed -- its constructor is currently running. It is probably being thrown by the BlockCopy method (you can inspect it in Reflector to see under which conditions it throws this exception). In the process of running the constructor, a satellite resource assembly is being loaded to get a string (which is probably the human-readable exception message).

That is an easy one, fixed in the next Template release. https://christoctemplate.codeplex.com/discussions/440995
Basically, update your .DNN file to include the proper namespace for your BusinessController class, I left a hardcoded one in there by mistake in one of the templates.

I know this thread is pretty old now, but I just wanted to say I just had the same exact exception, and the solution was also pretty much the same.
The event viewer had the same output as in Joe's case.
I managed to catch the exception in VS and it showed me a "ResolutionFailedException while setting value for property Views.MainWindow".
The real problem however was that entity framework tried to build the SqlCE database in a directory that did not exist.. Pretty basic, but the exception was so weird I though i would share my findings.
