Qnap [ Ubiquiti UniFi ] Wi-Fi Management

J'espère qu'il est acceptable d'écrire en anglais - je n'ai pas trouvé d'autre forum pour discuter du QPKG UniFi.

RESOLVED: I got it working by uninstalling and re-installing MongoDB. It seems it had become corrupted somehow.

I have been running successive versions of this QPKG for years. Suddenly, my web interface was unresponsive and a restart of the app did not change this. I then noticed that Unifi was using 60% of CPU. I uninstalled 8.2.93.0 and tried installing 8.5.6.0. This did not change anything. I uninstalled and did a fresh install of 8.2.93.0. I let it run overnight and still this morning the web interface said "Unable to connect" and Unifi was using 60% of the CPU with three java processes (all showed as "Sleeping"). I have MongoDB 4.4.18 installed.

I removed the QPKG and reinstalled 8.5.6.0. It has been running for two hours, both the CPU and the memory is growing continuously (now 40% and 300 MB) and the web interface says "Unable to connect".

What could I try to diagnose the root cause?

P.S. I decided to stop the app since it had reached 400 MB RAM and was using 45% CPU. Even after stopping it, it stays in the list in Resource Monitor. I have to manually kill it from SSH. Is this normal?
