Yay, "my" bug. See #3 for a more thourough explanation what's going on.
This is likely a symptom that you have some performance issues, and the processing toolchain at some point is not able to run in real time anymore. Essentially, rtl_daq.c can't write the data fast enough to the downstream steps, so you either need to accept the data loss that you experience right now, or you need to improve performance somehow.

Is your Pi4 running any other tasks, or possibly thermal throttling? Generally even with this warning you shouldn't get any problems, but if the Pi4 is really strained it could end up causing a coherence desync.

It ended up being a power issue. The Kraken sure is hungry.

To clarify, was it that Kraken wasn't leaving enough power for the Pi4 on your supply, so it throttled?
from heimdall_daq_fw.
It appears so. The power supply I was using is supposedly good for 3A per port, but it seemed to struggle regardless. I've moved to a new power supply that has a built in volt and amp meter. No issues since the upgrade.

Can I have the model number of the non-working supply? Maybe it has some total power output limit across all ports.
Want to make a note in the documentation if there are some supplies like that.
