Application: Exis.eXray.AppServerService.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.InvalidOperationException
Stack:
at System.Runtime.InteropServices.GCHandle.get_Target()
at Devart.Data.Linq.c.j()
at Devart.Data.Linq.i.a(Int32)
at Devart.Data.Linq.g.a(a)
at Devart.Data.Linq.g+a.b()
The only thing i can provide as a help, is that i use the:
configuration for my service.

The problem appears to be caused by the peculiarities of the Garbage Collector work. If this issue can be reproduced more or less reliably, please send us a test project so that we are able to investigate it in details.
This Windows Service is our Application Server for our CRM system. The solution has 23 different projects, 10 of which are console applications loaded in different application domains according to user preferences. Most of these console applications, host WCF services.
It is apparent that there is no way i can create a test project for this! For simple projects, everything works ok. The complexity is the problem.
I can give you more information about the way our application server is architectured if you like. I can provide you with our Team Licence information if you think that maybe i don't deserve better attention, i can switch to email and abandon the forum, but PLEASE, PLEASE, don't ask about a test project for a Garbage Collector related error!!!

I have this error also from time to time on our IIS server on version 5.60.124. This occurs in some background thread and completely crashes the server with no error message.
It looks like dotConnect for Oracle does not work quite well on heavy multithread load.
As you cannot reproduce it, why don't you just catch this error and handle it. Output something and on some log file and don't crash the application.

I tried the latest beta version but i hit the error described by me on an other message : http://www.devart.com/forums/viewtopic.php?p=63226. This prevents me from using the beta version in production environment, so i'm stuck with the problem. I hope that you will fix my issue as soon as possible in the next minor release of 5.XX line which i hope will be more stable than the new 6.XX line.
