Hello,

I have recently upgraded the gateway from 8.0.14 to 8.0.16. however, the gateway is not running (frozen for more than an hour). I restarted the ignition service but no luck. I also tried the 8.0.16 installer again and got the same error. Kindly advise.

You’ll probably need to look for relevant errors in your wrapper.log file.

Hi pturmel,

Here is a screenshot of the wrapper.log.

Can you upload the entire wrapper log somewhere we can take a look at it?

zip it first and then try again?

If that doesn’t work let me know and I’ll DM you a Dropbox link to upload to.

Ok, there appears to be a stack overflow error originating from one of the Cirrus Link modules:

As a workaround you can try removing the MQTT modules from the `$IGNITION/user-lib/modules` folder and then start the gateway again. If that works you can reinstall them and see if things are working. You might also check to see if there are newer MQTT modules available to install.

@wes0johnson may be able to comment on whether they’ve seen this before.

This isn’t something I’ve seen before. I’d be interested to know the MQTT Engine version. How many tags are present in MQTT Engine? Also, are there UDTs being used in MQTT Engine?

no UDTs were used. the total number of tags in the engine did not exceed 500.

If you have a shell on the EPIC then you can navigate to `$IGNITION_INSTALL/user-lib/modules` and delete the Cirrus Link modules.

Not sure exactly where the `user-lib` folder ends up on those devices.

Thanks for your reply, how can I find out if there is a shell on the EPIC device?

I don’t know anything more about these. Do you have any way to SSH into it and get a command line or run commands somehow?

SSH requires additional license which we do not have!

Sorry I’m not sure how to further help you. Honestly I don’t even know which company’s support department you should contact at this point. I imagine ours would just ask you the same thing about SSH access…

Hi melwadeya (and anyone else viewing this reply)-

SSH (shell access) licenses for _groov_ EPIC and _groov_ RIO are available for no charge directly from Opto 22. You may place your no-charge order online from this page:  
[https://www.opto22.com/products/product-container/groov-lic-shell](https://www.opto22.com/products/product-container/groov-lic-shell)

Or simply start a chat or call Opto at 800-321-6786 to place the order.

Upon completion of the order for the free license, you’ll receive an activation key that you’ll activate to your EPIC or RIO via the [manage.groov.com](http://manage.groov.com) Portal. Download the license file, apply it to your controller or I/O, and you’ll be all set.

For anyone experiencing difficulty with Ignition Edge running on our _groov_ EPIC or (future version of) _groov_ RIO, our Product Support is **free** via online chat, email, or phone:
