MX b3088
running on W10 laptop
I have just updated this instance from 3072 - which was running fairly reliably.
I have been updating another installation of a friends laptop running ubuntu/Mono and a WLL. After a lot of help from Mark this is now running fine for days on end.

Yesterday I updated my install and have started to get FTP issues - similar to those experienced on the Ubuntu version.

Code: Select all

2020-07-15 08:44:33.850 Realtime[50]: End cycle

Looking at the logs over a period, my FTP cycles normally complete in about .5 of a second

Code: Select all

2020-07-15 08:43:34.654 Realtime[48]: Start cycle
2020-07-15 08:43:35.172 Realtime[48]: End cycle

Obviously there was some kind of issue on the server that caused the FTP to fail in cycle [50]

From that point onwards successive attempts continued to fail

Code: Select all

2020-07-15 08:44:34.669 Realtime[51]: Start cycle

At this point [51] stops and [52] starts a new cycle

Thanks. So close!

It is doing what I expected now, on failure it tried to disconnect (failed), tried a reconnect (failed), established a new connection (worked).

But it had fallen through to some exception catch code at that point, and that does not clear the FTP in progress flag, so subsequent real time FTP cycles failed. I need to add clearing the in progress flag to the catch code and it *should* work as intended. That will be in the next full release.

Hi Mark
Excellent, thanks
as a side note, I checked the connectivity of my FTP server whilst MX was having issues, and got in fine.

Cheers

MX Started at 08:27
Connection first failed at 08:44 - successfully reconnected.
Disconnected again at 09:10 - successfully reconnected.
Disconnected again at 09:27 - successfully reconnected.
Disconnected again at 09:30 - successfully reconnected.
Disconnected again at 09:33 - successfully reconnected.
Disconnected again at 09:54 - reconnected, but hit the bug in MX.

So it doesn't look like the SFTP connection to your host is terribly reliable.

Also noted in that log file that there is problem with your dayfile at line 2117 that needs fixing.

Hi Mark
The error that I could find in the diags referred to line 2117 in Jul20log.txt

I have looked at the relevant row, and compared it to others and I cant see any problem with it.
Could you have a look for me please...

Sorry, yep, wrong file name - and nope I cannot see anything wrong with the file either!

I also tried the file in my dev install and it read it without error.

The other thing is that you are forcing the console to send the entire logger contents on start-up because the console log interval is set to 30 minutes, and MX is using 5 minutes.

Hmm, I didnt know I was doing that. Secondly I cant even find a setting where I can change that. It was not a conscious decision.

You have to change the console logger interval from the WeatherLink software, or fire up a terminal emulator and send it the command...
SETPER 5

Where 5 is the interval in mutes.

Doing this will clear all your logger history.

Hah
Thanks for that, would never have guessed to look there!
