Nightscout sync is skipping/losing a minority of insulin treatments

A seemingly random subset (maybe about 10%?) of insulin treatments are missing from my nightscout instance. I was only keeping 3 months of data in xDrip+ and based on a few spot checks it seems to affect the whole time range.

I've been using the NovoPen insulin pen NFC to enter most treatments. I have no idea if that's a factor, but I mention it just in case.

Obviously the usual troubleshooting steps don't apply, as most of my data does arrive. As far as I know my network is fairly reliable.

Can anyone suggest how I can query the xDrip database to get counts of treatments for certain time ranges, and investigate if there's any specific patterns in the records not being uploaded?

I haven't tried a backfill yet - I'm a bit hesitant to backfill my entire DB until we get more info about the state it's in now.

Note: could be related to #2900? I haven't found any other associated issues yet.

PS. Yesterday was weirdly much worse... it missed 3 in a row (which is why I started investigating), from 2 different scans.

Here are my logs for the 2 scans that never uploaded. These don't seem any different to what's normally logged.

(Just to clarify: I say "3" because I'm counting non-priming doses. So it's really 6; the priming doses were not uploaded either.)

Please confirm that what is missing in Nightscout is present in xDrip.

Let's enable detail logs so that hopefully, we get more clues:

Go to
Settings −> Less common settings −> Extra logging settings −> Extra tags for logging

Enter the following:
UploaderQueue:v

Please go to the logs and confirm you see some new logs with heading "UploaderQueue" once every 5 minutes.

The next time you have a missing point, let's see the logs.

Thanks for that. I turned that on, but didn't see a problem in the first couple of days, and I won't be using that feature for a while now (I'm trying something with a pump).
