We're observing that the APPUiO Application routers have increased process counts and memory usage leading to infrequent unplanned router restarts since yesterday (2020-05-27) afternoon at around 15:00. The symptoms suggest that this is a reoccurrence of the issue we reported in https://status.appuio.ch/incident/239.
We are currently investigating potential long-term measures to prevent this issue from reoccuring in the future.
Until we find a solution, applications may experience brief connectivity interruptions when one of the application routers is killed and restarted by the operating system due to its high memory usage.
2020-05-29 16:35: We identified the source of the increased amount of long-lived connections on the application routers and were able to resolve the issue. Right now the application routers look stable. We are continuing to observe the situation.
2020-06-02 09:35: The situation remained stable over the weekend. We're considering this issue resolved for the time being.
