-ERR command not allowed when used memory > 'maxmemory'

[Tharon]

My app works fine until
1) the rhosync/redis server has been running for a while
-OR-
2) multiple devices are connected

I get the following debug output from the RhoSync Heroku logs when I
connect my second device:

Is there something wrong in my code? Is there a memory cap in the free
account so this would be easily solved by migrating the project to our
production account?

thanks!

Hello,

Nothing wrong in your code, the free rhosync apps come with 5MB of storage.  We have production-level plans which include more storage, please see http://rhohub.com/pricing for information about the plans.

Thanks Lars!

This is good news :) I have moved our code over to a premium account,
but am still getting a similar error:

The data file for this is only 168kb as a JSON file in plain text, so
I'm sure it's not taking up all 500mb of space. Any ideas? The above
output is when attempting to log in from device #3.

Hi Tharon,

I have fixed the instance below so it should be running now with the proper redis storage.  Sorry about that!

-Lars

[Tharon]

Hi Lars,

We are again having the same issue as above, but this time on our
production account. The JSON document that is served up by the
webservice contains only 128kb of data, and we have an account that
should allow for 500MB. This should be generous space for this amount
of data, even with Redis' in memory data. There are currently four
devices connected to the RhoSync instance.

Let me know if you need more information!

Hi Tharon, yes I will need info on the app / project name to debug it further.  Please file a support ticket from your rhohub dashboard (clicking on the "Support" link at the top).  This way you can include sensitive information in there.

Thanks,

Lars

Hi Lars, it turns out that the issue was that when I redeployed the RhoSync app, the "Live App" button was still toggled as on. However, the app only showed 10 available devices. Toggling the button back to off, then toggling it again so it showed on resolved the issue. The app now shows the correct 100 device max.

Thanks!!!
