Weewx log shows errors and images are not generated

I am receiving the following error messages when running weewx on a RPi with Vantage Pro2.

Hi,

I know the log extract shows the error message(s), but could you post the entire log for a couple of complete archive periods.

Hi Gary,

This is kind of embarrassing, but how/where do I find the entire log for a couple of complete archive periods?

Rune.

Let me know the make of your weather station as I am concerned that you may have some crazy data.

Hi Rune,

You will usually find the WeeWX log entries in /var/log/syslog unless you have modified your install to put WeeWX log entries in another file (/var/log/weewx.log is commonly used). What we are after is at least a couple of cycles of saving a record to database and running the report suite.

Here we go  :-)

Hi Gary,

Did you have time to look at the logs?

Rune.

Hi Rune,

My apologies I did forget you, an internet outage for a couple of days and by that time your post had dropped down the list. No excuse though.

Having a look at your log I suspect you may have corrupt station memory. If you look down the log around 17:00 25 July you will see that no archive records are being read from the station and consequently no archive records are being saved to database. Have a look at the Corrupt station memory section in the User's Guide. There are a couple of suggested fixes there, first try fix 1., power off to the console. Restart WeeWX and see if it runs error free. If you still have the same errors try using the Dump the logger memory, this won't fix the problem but it might help prevent loss of data when we do the next step. Once you have dumped the logger memory try fix 2., clear the console memory. Again restart WeeWX and see how it goes.

One other thing you might consider is a real time clock for your RPi or failing that delaying the WeeWX start until NTP has properly sync'd your clock. There are couple of instances of the station clock being reset in the log you posted, probably did not cause the issue you currently have but it can cause issues for WeeWX. If you don't go down the realtime clock path there are a number of threads in the forums on delaying the WeeWX startup, one only last month or so I think.

Let us know how you go.

Hi again,

Lost contact with my station and will not have possibility to check it out before end of August.

I have had similar incidents over the past year. I swapped the RPi to the latest version some 6 months ago and it seemed to work for a while.

How likely is it that the station memory is corrupt beyond repair?

I have tried powering off the console a number of times and I have cleared the station memory. This seems to have fixed the issue for a short period of time.

Real time clock on the RPi might be my next attempt unless it is likely that the station is corrupt beyond repair :-(

Hi,

I have a Davis Vantage Pro2 weather station.
