not reading data after reboot

[slaterson]

i have weewx running on linux, it's been going fine for a while (recently switched from wview to weewx 4.8.0).  i configured weewx  to write to mysql (localhost) which has been working just fine as well... up until yesterday.

i needed to unplug the server where weewx is running, it was powered off for about 30 minutes.  the weather station (a davis vantage pro 2) was also powered off during this time.  upon restarting the server and power station, weewx reports no errors in the logs, however isn't archiving any data from the vantage.  i tried upgrading to 4.9.1, same experience - no data being updated, no data being written to the database.  i then tried pointing it to sqlite, and same, no data written.

i then did a fresh install of weewx 4.9.1 to a new directory, configured, it and ran with the defaults.  it sees the weather station, reads data from it's logs, however only up to the point where the server and power station were powered off.  all data since is not read, as if it's not there.

the weather station console shows the current conditions, and the output of weewxd when run from the command line shows the loop process getting updated data with every read - the output changes as the temperature changes, etc...

here is the syslog entry when i startup weewx (this is it, i have tried various debug settings and nothing provides more info):

here is example output of weewxd when run from the command line (outTemp changes as the outside temp changes, as do other values):

i'm at a loss as to what is happening.  it was working fine, rebooted, and it doesn't collect data any more.  i have rebooted since moving to weewx and things were fine.  main difference this time is the weather station was powered down.

Lets start by setting debug=1 and restarting weewx, then giving us the debug logs please.

Your logs should look a lot like the following with lots of DEBUG messages....

Give us everything starting with:

and down til at least the part where it seems to hang similar to:

Can't say for certain as you cut the log extract before WeeWX attempted to download any archive records, but I am guessing you have corrupt station memory. It is not uncommon when there is a power interruption to the station and it manifests itself as loop packets continuing to be generated but the station will not provide and archive records. No amount of restarting WeeWX will correct it as the problem is in the station/logger.

I suggest you work through the Corrupt station memory section of the Troubleshooting Davis Stations wiki page.

regardless of the value i add for debug, even debug=1, i get no more info in the logs than what i've shared.  it's odd.  i've found others that have reported the same.

[slaterson]

this did the trick, thanks!  was even able to get away with no data loss, amazing!

ran a --dump, verified the data was be added to the mysql db (it was), then did a --clear-memory.  after restarting weewx, everything is in order.
