CSSPP-GEO errors

Post by ve2fxl »

Hi last week and still underway, I have errors in my G16 images (missing blocks) and they follow a pattern. I receive with CSPPGEO then feed to GEO2GRID. I don't know if it's related to the following GRB issue message sent by NOAA last week:

Update #1: The intermittent degradation (subtle horizontal stripes) of GOES-16 ABI Band-16 products continues. Engineers are aware of the problem and a solution is being discussed. Corrective action may occur as early as Friday the 27th of November.

But I checked on another GRB station that isn't using CSPP-GEO and I don't see any of those errors. I didn't have any GRB CADU error today yet so can't be that and the pattern (missing blocks are nearly always at the same places). Easy to check the errors in CONUS sector.

When it happens, a lot of the following errors are written in grb.log (especially the invalid time portion):

jvm 1 | 2020/11/29 14:27:15.035 | [ERROR] (GRBReceiver) Should never happen, invalid time portion of product key:
jvm 1 | 2020/11/29 14:27:15.035 | [ERROR] (GRBReceiver) Unable to route packet for key APID: 480, last product time seen: 0x480_2020-11-29T19:25:17.355

jvm 1 | 2020/11/29 14:27:15.035 | [ERROR] (GRBReceiver) Should never happen, invalid time portion of product key:
jvm 1 | 2020/11/29 14:27:15.035 | [ERROR] (GRBReceiver) Unable to route packet for key APID: 480, last product time seen: 0x480_2020-11-29T19:25:17.355

and after the invalid time portion errors, those:
jvm 1 | 2020/11/29 14:27:15.037 | [INFO ] (GRBReceiver) New product for Key: 0x480_2020-11-29T19:26:58.312

jvm 1 | 2020/11/29 14:27:15.437 | [ERROR] (GRBReceiver) APID: 0x9f sequence error, counter: 16243

So I uploaded also the image corresponding to those errors

So do you think it's only me or is it from GRB stream or CSPP-GEO bug or misbehaving?

Thanks

Hi Luc -

We don't think this is related to the alert from NOAA. Our systems behaved normally during this time period so our first suspicion is either:
  • * You are experiencing some local interference
    * Your machine is overworked to the point it is not keeping up with the data flow
If you are able, the best first step would be to run the cspp-geo-grb-diag.sh script, in the base CSPP-GEO install directory, then
email us the output (removing any info you might consider sensitive).

We will await your response or further questions.

Thanks,

Can you tell me the email address to send the log?

After a Dec 22nd email exchange with Luc, we have determined the problem is upstream from CSPP Geo GRB,
either a cable or NIC on their GRBStreamer PC.
