[OZAPRS] BOM Feed gone out of control

[Mathew McKernan]

Hi all,


It seems this was due to the WXSVR server being offline for a period of time (around 2-3 weeks) with beacons queued, but then cancellations as well (hence the unusual coordinates which are in fact deletion of objects). The scripts that fetch data from the sources such as CFA/RFS/TFS/BOM go into a database, then the wxsvr/wxbot-au components transmit the data out.


I've cleared the cancellation beacons from the database which is the cause of this steady stream of data and backlog.


I will be making some modifications to wxsvr/wxbot-au to ensure this doesn't happen again by not sending out overdue cancellation beacons.


Sorry for the situation everyone, it is not good enough and sorry for not seeing this post until this afternoon, again, poor on my behalf.


I have been active on this list but route all the mails to a mailbox. An email to me directly may have triggered a more responsive reply - I have also added details to the website, an oversight on my behalf when setting this up originally.


73's,


Matty

Yes somethings is wrong. Theres basically a continual stream of jibber comming out of the server now. Its very delayed with its time stamps.
I first noticed this last night arounf 1800 local time as the iGate was continually transmitting here with excessive traffic. I only gate relavant South Australian WX traffic here to RF and thats been the case for years now.

I am logged into first.aprs.net.au currently with e/WXSVR-AU amongst other things. If I single out the WX feed then it consists of an almost constant stream off the internet of about 1kb/s on average. This is everything for the whole country in WX data.  I dont beleive historically it was anything like this. It was basically much quieter.
The time stamps are slowly advancing but from what I can see its currently about 8Hrs behind. Last nights data was irrelavant and incorrect in that in SA we had Current road WX alerts, Strong wind Warnings and Sheep grazier alerts according to BOMs web site. What the feed was showing on APRS was all these things in a cancelled state repeatedly and constantly.

It appears that the WX feed is just overloaded and Buffered and attempting to play catch up but in reality I think its failing and just dumping it all to the server at a rate slow enough that it may never clear the buffer.

Another curiosity is something observed here http://second.aprs.net.au:14501/ where the callsign WXSVR-AU is logged into the Tier 2 server from IP 59.167.198.98
This has been logged in since about 1800 local time last night (when I first observed the excess traffic) and is watching amongst other things its own feed from WXSVR-AU . The filter is b/WXBOT-AU g/WXBOT-AU b/WXSVR-AU g/WXSVR-AU g/VK3MJM-15 b/VK3MJM-15

So what is this WXBOT-AU software package doing watching its own callsign and feed ? Its showing a lot of RX packets and a lot of Duplicate packets for something thats only been logged in for less than 15 hrs.
