What could this blank error message mean? I get it randomly in my LOGS. I am using non-cookie sessions. it occurs randomly in all aspx files..
code handler outputs:
objErr = Server.GetLastError().GetBaseException()
Server.ClearError()
Error Message: & objErr.Message.ToString())
Stack Trace: & objErr.StackTrace.ToString())
output
Error Message:

Is this an inner exception that you are seeing?
regarding ToString():
If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not a null reference

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
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); }

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 am working on an application that need to do asynchronous tasks.
I use two times the code given at http://msdn.microsoft.com/fr-fr/library/system.web.ui.page.executeregisteredasynctasks.aspx
I simply copy and paste it in my application.
Unfortunately I have an error thrown on one time while the other one works perfectly.
The error is :

This typically happens when you have to many Report instances open. We had the same issue using C#/Crystal Reprots trying to generate multi threaded reporting. You have to ensure that you close and dispose of the report properly once done with them.
