Subject Re: [Question] [Issue] Undeploying and deleting an application
Date Mon, 06 Apr 2015 04:55:56 GMT
Hi Udara,

Thank you for the quick responses and verifying the above.

I did as you mentioned:

   - Undeployed the application then waited a couple of extra minutes after
   the undeployment was completed.
   - Next deleted the application and waited another couple of minutes.
   - Thereafter the removal of cartridges and cartridge groups worked
   accordingly.
   - But when trying to remove the auto scaling policy I was faced with the
   same issue we discussed above. (This was what happened before too.)

Assuming there is an issue with the autoscaling policy and its removal
process,because that's where this issue comes up? Letting you know on this
regard.

Thanks & Regards
