What's the exception? You can see some of the source at:
https://github.com/mono/mono/blob/mono-android-1-0/mcs/class/System/System.Net/WebConnectionStream.cs#L76
https://github.com/mono/mono/blob/mono-android-1-0/mcs/class/System/System.Net/WebConnection.cs#L486
Full stack trace + exception type + message may be helpful.

That's ignorable. We should probably just stop emitting that message; I'm not
even sure why it happens (as in, I've read Android's source and can't fathom
how we're getting a return value that would prompt us to generate that
message...).

You could always file a bug. :-)
I am also reminded of:
https://bugzilla.novell.com/show_bug.cgi?id=648862#c9
in which things went bad because network resources weren't disposed of in a
timely fashion. Perhaps you could look for some HttpWebResponse/etc. instances
and ensure that you Dispose() of them when you're done? Mono's networking
infrastructure doesn't seem to like/appreciate having "too many" network
connections "in flight" at once.
