Description John Hargrove 2011-11-17 23:05:58 UTC
I am running mono 2.10.2 on OpenSUSE 11.4 x86-64.

I have a WCF-based service that responds to WebGet requests. Occasionally, and almost always when executing a particularly long request, my application will crash and an unhandled exception will be dumped to STDERR.

The service may run for days without encountering this problem. The exception looks like this:

Unhandled Exception: System.ArgumentOutOfRangeException: Argument is out of range.
Parameter name: timeout
  at System.Threading.WaitHandle.WaitOne (TimeSpan timeout, Boolean exitContext) [0x00000] in <filename unknown>:0
  at System.Threading.WaitHandle.WaitOne (TimeSpan timeout) [0x00000] in <filename unknown>:0
  at System.ServiceModel.Channels.Http.HttpListenerManager.TryDequeueRequest (System.ServiceModel.Dispatcher.ChannelDispatcher channel, TimeSpan timeout, System.ServiceModel.Channels.Http.HttpContextInfo& context) [0x00000] in <filename unknown>:0
  at System.ServiceModel.Channels.Http.HttpListenerManager.TryDequeueRequest (System.ServiceModel.Dispatcher.ChannelDispatcher channel, TimeSpan timeout, System.ServiceModel.Channels.Http.HttpContextInfo& context) [0x00000] in <filename unknown>:0
  at System.ServiceModel.Channels.Http.HttpReplyChannel.TryReceiveRequest (TimeSpan timeout, System.ServiceModel.Channels.RequestContext& context) [0x00000] in <filename unknown>:0
  at System.ServiceModel.Channels.ReplyChannelBase.<BeginTryReceiveRequest>m__1A (TimeSpan tout, System.ServiceModel.Channels.RequestContext& ctx) [0x00000] in <filename unknown>:0

I have not determined a workaround. I can say that this -seems- more likely to happen during long-lasting requests, such as those which return a large amount of data over a slow VPN connection. This would suggest to me that this may be related to multiple concurrent requests to a service, but that's speculative.
