Hello Team,
I would like to ask your help in a technical issue. I am creating an AI chatbot flaskbased application , where using mostly open source libraries. For semantic search and ranking I am using FlashRank library (https://github.com/PrithivirajDamodaran/FlashRank ). A month ago I deployed as Azure App Service, I tested it several times , and worked properly. In spite of the earlier deployment success at the moment I am facing issue, the app doesn't work properly it stops functioning when calling the function which fires the FlashRank. I tried using different Virtual Machines or Container Instance, but experienced the same issue. I checked Kudu and log streams, but I haven't received detailed description about the issue. Always someting like this:
2024-05-23T13:17:54.8054943Z [40m[1m[33mwarn[39m[22m[49m: Microsoft.AspNetCore.Server.Kestrel[22] 2024-05-23T13:17:56.3435109Z As of "05/23/2024 13:17:39 +00:00", the heartbeat has been running for "00:00:01.[9722283]" which is longer than "00:00:01". This could be caused by thread pool starvation. 2024-05-23T13:19:30.3993582Z [40m[1m[33mwarn[39m[22m[49m: Microsoft.AspNetCore.Server.Kestrel[22] 2024-05-23T13:19:31.3647632Z As of "05/23/2024 13:19:18 +00:00", the heartbeat has been running for "00:00:03.[1978528]" which is longer than "00:00:01". This could be caused by thread pool starvation.
I created logging for debugging and it turned out the the stop happens when calling Flashrank, the logging message after the flashrank function can't be reached.
Can you suggest solution solving this, and help me understand what happened that all of a sudden the app service doesn't work as used to be.
Thanks you help in advance,
Viktor Banai
Hi @Viktor Banai,
Since you are using 3rd product in your project, it's hard for us to check the issue. I also found you raised a github issue.
If you want know what happened in azure, could you create a brand new repo which can reproduce the issue for us to check ? Then we can test in our side.
Best Regards
Jason
Hello Jason,
I truly appreciate your response. :)
This is the new github repo I have created: https://github.com/vbanai/ChatBot_onAzure
Now I deployed it as an Azure App Service but it didn't work, even if I upscaled the plan to a premium tier. However it worked a month ago on the most basic tier.
This chatbot application would be for a music store in Hungarian language. If you test it please write someting into the webchat surface like "Zongora kapható?" this means "Do you have piano available on stock?" or "Gitár kapható?", "Do you have guitar available on stock?"
Thanks your help in advance,
Viktor Banai
One more thing Jason, now I have deleted the app service created with premium tier, but if you need I can create a new one connected to the new github repo.
Hi @Viktor Banai,
Since you are using other services(like chatgpt and PostgreSQL ), it's hard for me to test it. And you also mentioned it works before in Basic Plan, it my be code issue in your project. We can find more details by checking the logs.
You can refer my suggestion via the link below.
Best Regards
Jason
Thanks Jason, locally the code runs properly, and if I got back to the earlier commit which worked fine, now it doesn't work. Okay, I try to build my app from scratch again and change tier if needed. Let's see how it goes.
Best wishes,
Viktor
