Hello everyone,Over the past few months, I have noticed an issue over at the College of DuPage, and at a company I work for on the side. In our ldmd.logs, on our NOAAport satellite ingesters only, we see something like this every 15 or 30 minutes:
Jun 6 15:46:57 sat noaaportIngester[5561] WARN: Gap in packet sequence: 29680041 to 29680050 [skipped 8] Jun 6 15:46:57 sat noaaportIngester[5561] WARN: Gap in packet sequence: 29680041 to 29680050 [skipped 8] Jun 6 15:46:57 sat noaaportIngester[5561] ERROR: Missing GOES fragment in sequence, last 37/169677 this 46/169677 Jun 6 15:46:57 sat noaaportIngester[5561] ERROR: Missing GOES fragment in sequence, last 37/169677 this 46/169677 Jun 6 15:46:57 sat noaaportIngester[5561] WARN: Gap in packet sequence: 29680050 to 29680055 [skipped 4] Jun 6 15:46:57 sat noaaportIngester[5561] WARN: Gap in packet sequence: 29680050 to 29680055 [skipped 4] It only happens with satellite imagery, as I see no other data losses in both receiver's logs. This happens on LDM 6.12.6, and also on 6.12.13. It is not consistent; that is, quite a few times the images will come in fine. On both sites, the C/N is above 17, and signal strength is excellent, around -37 to -39 dB. Is anyone else seeing this? I wish when this happens, and if it's possible to parse it, we would be able to see the WMO headers of the offending data to track this down better.
