Problems with REST API and asynchronus ucs creation

Hi all, I'm struggling using asynchronus tasks to generate a UCS. I've been through the API reference, and tried exactly what they suggest but something isn't right. I've dug through logs, watched l...

    Thank you for that, I had come across it before but didn't think it fit since my version isn't listed as an affected version, I'm running 16.1.3.3.

    I do see TimeoutExceptions all over the restjavad.x.log, for everything I try to do.  The POST to create the task, which is successful, the PUT, and the GET to check the status.  So it seems that either the system is able to recover from that status sometimes, or sometimes it's just a meaningless message.

    The bug lists icrd being busy as a requisite, but this is on 2 different pairs of lab devices.  The ones I tested this morning are idle, like.. 0 connections for the last few days idle, and I am the only person sending any kind of API requests to them. 

    The bug also has no resolution, do you happen to know of any fix?  We're currently generating ucs archives and downloading via central bash scripts that I'm seeing occasional issues with, and I'd like to move to using the API.

        Thank you for that suggestion,

        This is not a direction I can go at this time.  I need to be able to initiate from and pull to a central location for hundreds of devices.  Installing and maintaining an iapp on each device is not sustainable for us right now.

      can you generate the UCS via iControl REST synchronously without the task? If so, I'd suggest opening a case to inquire.

        Tried a non task ucs save, and it also failed after sitting a while waiting on a response. Looks like support is my only hope.

        ❯ curl -k -u apiadmin:<redacted> -H "Content-Type: \
        application/json" -X POST -d \
        '{
        "command": "save",
        "name": "myUcs"
        }' \

        I can see it started, but didn't make it as far as the task request did.  It didn't get zipped up

        Tried it from tmsh, just in case something was majorly broken :

        Seeing the same TimeoutException errors from the non-task request as well
