Bug: Applications disappear from the UI several times a day

Hi,

We've been seeing an issue where the Applications page randomly becomes empty several times a day. The UI shows No applications found, along with the message about Prometheus cache lag and synchronization in progress. After sometime the time increases, and after half an hour everything comes back again; it's become a daily routine to wait for the application to come back

The strange part is that nothing actually seems to be down. All Coroot containers are still running, there are no restarts, and Docker looks completely healthy. After a few minutes, everything comes back on its own without us doing anything.

And FYI, the hardware configuration that we have is about 34 GB of RAM, 16 cores and 500 GB of storage

Is this expected behavior, or could this be a bug in the synchronization process? Is there anything we should check on our side?
