Hi Team

We are using confd version 8.0 and saw below crash once while schema upgrade(MAAPI_PERFORM_UPGRADE) was triggered.

Any pointers why the crash happened ? Please let me know if additional logs are needed.

Hi,
What specific 8.0 release are your running on and can you post the specific yangs that we see in the crash report?

Thanks @sbarvick

I see this when I run confd --version, does this mean this is 8.0 and there is no patch on top of this. In other branches of code where confd is higher I do see that this command outputs 8.0.14. So, I am certain that the issue is reported on confd 8.0.

[root@pod-cfgmgr-7b89f68c86-mqcvt /]# confd --version
8.0

Please find the YANG details here

module bgpmgr
{

    namespace "http://affirmednetworks.com/ns/yang/bgpmgr";
    prefix BGP;

    import tailf-common
    {
        prefix tailf;
    }

    import ietf-inet-types
    {
        prefix inet;
    }

Yes, that is the first release of 8.0. Is this crash happening all the time? There is not a lot to go on and it is a quite old release. Do you see the issue when running 8.0.14?
