QueueDeclare timeout exception

[Martin Pekurny]

I am getting a timeout when calling the QueueDeclare method. The stack trace is below. The details are that I installed 3.6.12 using the .NET Client 5.0.1 and get the error below. If I install the 3.6.10 version of the server I do not get the error. The code I am using is copy/paste from the C# tutorial at https://www.rabbitmq.com/tutorials/tutorial-one-dotnet.html. The installs are default, no plugins, no config changes. It doesn't seem to matter what version of the client (tried several, same results). However, when I use 3.6.11 or 3.6.12 it throws the exception every time I call QueueDeclare. Is there a change to the tutorial code to make it work with the new versions of the server?

Hi Martin,

I followed the tutorial one instructions and can't reproduce your issue. Here is my environment -

* Arch Linux, running .NET Core 2.0 (compile / run the tutorial code)

* RabbitMQ 3.6.12 (running from the stable branch of RabbitMQ)

It looks like you're using Windows to run the tutorial code. Are you also running RabbitMQ on Windows? If so, are you using the installer or binary release? Which version of Erlang? (that shouldn't really matter but you never know...)

Thanks -

Luke

Yes. I am running RabbitMQ on the same machine connecting with localhost. I installed it with the installer and have Erlang 19.3 installed. I also tried it with Erlang 20.1 on 3.6.12, but it made no difference in the behavior. Also, I used a .NET Framework console application instead of Core. I used a few different versions of the Client, 5.0.1, 4.0.1, and 3.6.12.

Thanks for the additional information. I will check this out on Windows tomorrow.

Hi Martin,

I just tried to reproduce this scenario using RabbitMQ 3.6.12 (installed via the .exe installer) and Erlang 20.1 running on my Windows 10 workstation, but everything works fine.

I used the code here: https://github.com/rabbitmq/rabbitmq-tutorials/tree/master/dotnet-visual-studio/1_Receive

At first I thought you might be having an issue with the windows firewall but with 3.6.10 working I'm not so sure.

Could you give it a try running the code from the repository I link to above?

Thanks -

Luke

Ok, I tried this on another computer and everything worked just fine. So it's something specific to my machine at work. I will attempt to uninstall everything in the morning again and start over. I will reply again with any more details tomorrow.

Hi Martin,

If you can, check to see if anti-virus software is installed and flagging the 3.6.12 .exe installer as malicious. Just an idea.

Thanks for the update -

So this morning I uninstalled RabbitMQ and Erlang. I then went through and deleted everything left behind by both installers. For RabbitMQ I didn't find much, a couple directories weren't cleaned up and the stuff in my profile. But for Erlang, it left some executables and processes running. After rebooting a couple times, I was able to remove them. After I was fairly certain I had gotten everything removed, I reinstalled Erlang 20.1 and RabbitMQ 3.6.12 and everything started working for me. I am guessing something left behind, most likely the executables by Erlang, were the cause of my issues.

So it looks like I am up and running again. Thanks for looking into this for me.

I have the exactly the same problem. I have installations on several  servers but only on my machine I experience this problem. After I restart broker and sometime delete the queue the problem is solved.

May I ask if it is possible to list all the steps you followed?

Thanks

I am having this issue as well, but only happen on my Laptop，not on my PC. After I restart broker it goes fine.

this is the log:

That exception simply means a channel failed to shut down in time and was forcefully terminated.

Nothing else. Not a whole lot of conclusion can be derived from it.
