Timeouts are not supported on this stream

[Khalid Abuhakmeh]

Hello, I recently looked in my logs and noticed an odd error. No one has reported this being an issue since it is in a logging filter and does not directly affect anyone, but I thought I'd put the stacktrace on here in case it is something more serious. Have you ever seen this error and what does it mean?

I am using Client 2160 (the obvious thing would be to upgrade, but can't do that just yet).

Do you have anywhere in your entities a Stream object?

No, non of my properties have streams on them. Super simple string properties and basic types. It is a random error too, so I'm not sure what could be causing it. Let me know what you might want to try and solve this issue.

[Oren Eini (Ayende Rahien)]

It looks like it is trying to serialize a stream somehow, at least, that is what the stack trace is telling me.

[Khalid Abuhakmeh]

Yep, you were right again. I thought there wasn't a stream, but I was trying to serialize an HttpPostedFileBase from the ActionParameters property in an ActionFilterAttribute. So this was my fault (as usual) :)

Thanks
