Okay, I think can explain the different behavior on dev versus QA. My
dev box is XP, which uses IIS 5, which has a limit of 10 connections.
This limit is being hit before the ScopeMachineryException shows up.
I have been able to catch and log the exception on QA. Here is the
stack trace:
ICallContextInitializer.BeforeInvoke threw an exception of type
Castle.ActiveRecord.Framework.Scopes.ScopeMachineryException:
Tried to unregister a scope that is not the active one
Stack Trace:
at
Castle.ActiveRecord.Framework.Scopes.AbstractThreadScopeInfo.UnRegisterScope
(ISessionScope scope)
at
Castle.ActiveRecord.Framework.Scopes.ThreadScopeAccessor.UnRegisterScope
(ISessionScope scope)
at Castle.ActiveRecord.Framework.Scopes.AbstractScope.Dispose()
at Rhino.Commons.ActiveRecordUnitOfWorkAdapter.Dispose() in c:
\SANDBOX\RhinoTools\rhino-commons\Rhino.Commons.ActiveRecord\UnitOfWork
\ActiveRecordUnitOfWorkAdapter.cs:line 100
at Mojo.Common.WebServices.UnitOfWorkContext.AfterInvoke(Object
correlationState) in c:\cruisecontrol\mojo\checkout\src\Mojo.Common
\WebServices\UnitOfWorkContext.cs:line 31
at
System.ServiceModel.Dispatcher.DispatchOperationRuntime.UninitializeCallContextCore
(MessageRpc& rpc)
Here is the class where the error occurs:
public class UnitOfWorkContext : ICallContextInitializer
{
private IUnitOfWork _unitOfWork;
public Object BeforeInvoke(InstanceContext instanceContext,
IClientChannel channel, Message message)
{
_unitOfWork = UnitOfWork.Start();
return null;
}
public void AfterInvoke(Object correlationState)
{
if (_unitOfWork != null)
{
_unitOfWork.Dispose();
_unitOfWork = null;
}
}
}
Thoughts?
