Working deloyment stopped working

[philip-kuhn]

Hi guys. We've been running a stock standard Azure Container Apps deployment successfully since December 4th 2023. Its been running fine with successful data querying, as of COB last Friday. Since Monday morning the container is crashing and cant start up. There is nothing I'm aware of that ran or was done on our side as part of an automated or human process that did anything to the resource. This is the second deployment that this has occurred with (ran well for a few weeks then suddenly the container started crashing) and I'm struggling to understand why. The log stream shows:

2024-01-17T06:32:52.25782 Connecting to the container 'qdrantapicontainerapp'...

If I browse to the file its looking for, in the Azure portal, its reported as being marked for deletion by an SMB client. As far as I know there was no human action that did this, and all other files are accessible. This is also the only fine that has contents. All the other LOG.old files are 0 size. We cant delete the file because its already marked for deletion, so I cant upload any sort of replacement file, so short of redeploying everything, I'm not sure where to go from here. I set the soft delete period to the minimum (1 day) in the hopes that once the file deleted it would sort itself out, but the file hasn't deleted and is still present but inaccessible. I'm really hoping I don't have to do a complete redeploy to fix this, so any assistance you can give to help understand why this has happened, would be highly appreciated.

Thanks so much

@philip-kuhn Is this still an issue? My team and I also added Qdrant as an add-on to ACA so you can just use that as well: https://learn.microsoft.com/en-us/azure/container-apps/add-ons-qdrant

If it is running or not working on ACA as a current deployment please file a support case

Hi Tara

When last I looked at it, it was. We needed to get our chat service up and running again, and I wasnt prepared to recreate the resource and restore the data for a second time, only for this to happen again, for a third time, in a month. We moved to Azure AI Search.

Thanks for your efforts
