Some instability

[stu_iow]

Been running Cumulusmx for about 2/3 weeks.
Just the last few days, I've noticed the last station update seems to get stuck, so requires a shutdown and restart of cumulusmx.
Both times that I have noticed MX gets stuck are about 16:00

I usually use the auto script to run MX.

I started mx without the script just now to see what infop it kicks out I I got this:-

System.IO.IOException: Write failure ---> System.Net.Sockets.SocketException: Th e socket has been shut down

Does that help with anything?

I'm running on a Pi2.

I'm using an IP logger on a Pi2, and it works fine for me, so I'm not sure what the problem is in your case. It looks like the TCP/IP connection to the logger is being disconnected, perhaps by the logger itself. Is your setup 'straightforward' - i.e. an IP logger connected to a router on the same network as your Pi2? Does your logger upload to weatherlink.com?

I use meteohub as a datalogger, that sends the data to the cumulusMX.

I will take a look at the meteohub, that also runs on a RPI2. I'll see if there any updates for it, then give it a reboot.

My setup is a VP2 via a RS-232<->wifi adapter and it works great unless there is a disruption in the connection (e.g., I power cycle the access point or the adapter) then the console outputs the error below.

Steve is there a way to catch this error and have it attempt to re-establish the connection?

Thanks,
Nick

Yes, I'm looking at trapping that error in the next build, and also adding a mechanism to try to reconnect the TCP/IP connection. There are a couple of very recent threads about this.

Thanks, Steve. Looking forward to the update.

Hi Steve,

It's not mentioned in your changelog but was this addressed at all in 3040?
Thanks

[steve]

No, I am only fixing Instromet problems at the moment.

[njc]

Ok thanks. I'll stay tuned.
