2 years ago is there any fix or suggestion for this exception? Facing same issue after some hours of service working, pattern is Dealer router, on Router side this exception happened
Code : smartDeviceRouterServer.Options.RouterHandover = true; smartDeviceRouterServer.Options.IPv4Only = false; smartDeviceRouterServer.ReceiveReady += SmartDeviceRouterServer_ReceiveReady; smartDeviceRouterPoller = new NetMQPoller(); smartDeviceRouterPoller.Add(smartDeviceRouterServer); smartDeviceRouterPoller.RunAsync();

Environment
Context
I'm using NetMQ for client/server comms for a pricing system using Pub/Sub for price data and Req/Res for C&C. It's working very well except that I'm seeing random and unreproducible exceptions occurring in the bowels of the NetMQ library in my client service.
It's possible that these exceptions are a result of network issues, but even so being able to handle that fault with out the service failing is mission critical.
Expected behaviour
Some way to suppress or handle exceptions within the internal NetMQ stack.
Actual behaviour
Unhandled exceptions causing the service to fail.
Steps to reproduce the behaviour
The client is using the following constructs:
NetMQBeacon in a NetMQPoller via RunAsync. SubscriberSocket in a NetMQPoller via RunAsync. RequestSocket directly via SendMoreFrame/TrySendFrame and TryReceiveFrameString/TryReceiveFrameBytes.
