Help Required - None of the specified endpoints were reachable

Hello All,

Though it is intermittent it is creating lot of noise in the system. The rabbit MQ version we have is 3.3.5, the service is restored after we restart the service broker and we .net framework 4.5.

Anyone has faced such issue in past?

Your application is out of memory. RabbitMQ simply reports that it was unable to connect,
without being particularly smart about what exactly the underlying exception is.

Thank Michael, but is there anyway to ensure thats its not a RabbitMQ issue as once the RabbitMQ service is restarted it works just fine.

Memory profiler can tell.

There is a known .NET client 3.5.x memory leak that's fixed
in nightly builds:
https://github.com/rabbitmq/rabbitmq-dotnet-client/issues/58#issuecomment-96074220

So you can either use 3.4.x or a nightly build .dll.
