aaronfeng opened a new issue #14053: URL: https://github.com/apache/superset/issues/14053
### Expected results If there's an issue with a single database it should not crash the whole system. ### Actual results A couple days ago we experienced a production outage when we noticed all of the web frontends (~10) were unresponsive and removed by the ELB. After restarting all of the web frontends we were able to load some of the pages. However, it became unresponsive again shortly after. Web server logs didn't reveal any obvious errors. Eventually we noticed the databases tab doesn't load at all after a rolling restart. It turned out that our Hive server were not able to accept new connections due to hitting its thread limit. After rebooting Hive server, Superset started to function properly again. We are running Superset 1.0.1 Docker image. #### Screenshots Didn't take any screenshots, but the Databases tab was completely blink as if it was trying to load. -- This is an automated message from the Apache Git Service.
