Hi Jiri@Jira

On rare occasions we found a null reference exception log inside our exception system.  During the FbRemoveEnvet.OnRemoveEventCounts it fails somewhere.

I've checked the code and the only place I can see failing is 

	if (RemoteEventCounts != null)
				{
					_synchronizationContext.Send(_ =>
					{
						RemoteEventCounts(this, args);
					}, null);
				}

how about rewriting that to
var evt = RemoveEventCounts;
if (evt != null){
  _SynchronizeContext.Send( _ => evt(this, args));
}

I'll try to include the pdb file with the exe to help you out.

thanks

a
