Quickest thing to try first: run _explicitly_ as administrator (right click on the ANTSGUI.exe). This kills 50% of bugs. -
On my side there's only a RedGate.Profiler.UI.exe. Ran that as Admin.
Unfortunately resulting in the same errors. -
Try the same but withholding the ASP.NET account details
-
Same results.

OK, thanks. Can you send to us (support@red-gate.com)
- Windows application event log (shows pertinent .Net errors)
- ANTS log (Help->Open log folder) -
It's probably the same error - w3wp crashes because of heap corruption and then the website is unsurprisingly not available (10061 is a socket error which usually means a requested service is not answering the connection attempt).
We would probably need a full memory dump to work out what was happening at the time of the heap corruption and I guess, try to prevent it. -
I sent the files to the provided address.
How do I create such a memory dump?
A colleague of mine has the same problem. We can browse our application. Browse the .svc. But when a call goes out to one of the Workflow based services.... BOOM!
We have profiled these services in the past... so it's interesting why this suddenly is happening. -
You can get a memory dump using adplus:
ftp://support.red-gate.com/utilities/autodumper.zip
Extract all files
Open a command prompt and cd to the extracted files folder
cscript adplus.vbs -crash -pn w3wp.exe
Should make a huge .dmp file in a subfolder of adplus
If you can actually get this to work, we can set up a private FTP to upload the dump to.
Sometimes the cause of this is a corrupt PDB and sometimes assemblies that use app protection or obfucscation can cause it.
I'd wager you can profile fine on "least detailed" mode, because all of the things that try to analyze the assembly so it can get line-level timings will not be executed. -
Adplus ends with the following line:

The least detailed profile does seem to create a more stable situation, but eventually, after a few minutes, the process randomly dies as well. -
Sorry but I don't think we will be able to troubleshoot this any further. I guess the .NET Framework is having some sort of issue?

First error
Second error
When profiling is off, everything works perfectly.
