not-applicable fix

Indeed! That's what happened due to the unclosed-and-recycled channels.

I'm creating a fix, but right now it regresses and cannot be applied yet.

The delegate is in channel which is disposed every time it finishes one
request-reply process and hence it should never glow up.

My point is that channel is disposed which should not result in growing up
irrelevant delegate stack. Note that it is not ServiceRuntimeChannel's event
but channel's event. If nonetheless still it does then the issue is not in
WCF. Or there is some explanation mismatch that blocks correct understanding.

If I add a:

Console.WriteLine (X:  + channel.GetHashCode ());

to ServiceRuntimeChannel:.ctor (), it prints the same value over and over
again, which indicates that the 'channel' object, which is a
System.ServiceModel.Channels.Http.HttpReplyChannel is somehow reused between
requests.

This is a WCF bug, from ServiceRuntimeChannel.cs:

public ServiceRuntimeChannel (IChannel channel, DispatchRuntime
runtime)
{
this.channel = channel;
channel.Closing += delegate { Close (); };
this.runtime = runtime;
}

The Closing delegate is added to, but never removed, so it grows bigger and
bigger, leading to a stack overflow in the Delegate:Equals ().

I can't reproduce this on linux, so this might be a windows only problem. If
the requests take longer and longer, that is usually a symptom of memory
growth, so its possible that the server simply dies because it runs out of
memory.

I re-ran my tests against mono 2.10.1 on Ubuntu 10.10 - the server ran longer
but eventually faulted with the following error:

  at System.MulticastDelegate.Equals (System.Object obj) [0x0] in filename
unknown:0 
  at System.MulticastDelegate.Equals (System.Object obj) [0x0] in filename
unknown:0 
Stack overflow in unmanaged: IP: 0x50d2bb, fault addr: 0x7fa710f87fe8

Stack overflow in unmanaged: IP: 0x48e287, fault addr: 0x7fa710f86fa8
exception inside UnhandledException handler: Object reference not set to an
instance of an object

This difference in results could be because you guys are running a newer code
line ; ) I will see if I can get my hands on the mono tip and re-try my tests.

This sounds like the race condition that was reported a few days ago about the
uses of Multicast delegate.

I am not sure if this is happening with user code, but it could be a missing
lock around a foo.Event += XXX code.
