reportengine Error - unrecoverable exception

[jmltech]

Can someone look at these errors I started to get today.  I had stopped weewx shortly to add the cmon extension.  I modified the cmon skin and default schema to change the network connection so that cmon would capture the appropriate net device.  I had restarted weewx and it created the cmon db and archive table correctly.  I used 'sudo service weewx stop' and 'sudo service weewx start' for starting and stopping.  When watching the /var/log/syslog for weewx errors incase I had a problem with my cmon install, I noticed this:

cmon graphs are working fine.
If I need to start over to correct... no worries.  This server has only been running weewx for 18 days, but without any errors.  I'm thinking it was something that I did with the cmon installation, but everything in cmon is working fine... archive records are being recorded and graphs are being drawn correctly.

Thanks, Joe

Hi,

The errors are coming from Weewx-WD, I doubt it is anything to do with cmon. Have you had any similar errors in your log before cmon was added? I seem to remember there was a bug in the current version of Weewx-WD that was fixed but perhaps not released. I will need to look into that. If you could provide a wee_debug report that would help.

Thanks Gary.  I did check /var/log/syslog before I stopped weewx to install cmon.  I didn't see any errors.  I had loaded weewx-wd right after I had installed weewx on this server (this is a new installation.  I have an existing VWS at another house that I'm planning on converting to weewx once I load the historic records over).  From the previous views from log files, I never saw any weewx errors.
Attached is the wee_debug log that you requested.

Ok, Joe, I think the bug I mentioned earlier is what is causing the problem. The simplest fix is:

• rename the existing /home/weewx/bin/user/wdSearchX3.py to, say, /home/weewx/bin/user/wdSearchX3_orig.py
• download the updated wdSearchX3.py from the weewxwd bitbucket site using:
  wget https://bitbucket.org/ozgreg/weewx-wd/raw/103afd92d02e1a343b3239fad828c45eb0689ead/bin/user/wdSearchX3.py
• copy the newly downloaded wdSearchX3.py in place of the old renamed, version
• stop then start weewx
• watch the weewx logs for any errors during the report cycle
• let us know ifd the issue persists

Gary,
Your solution (updated wdSearchX3.py) fixed the problem.  Been running all day and no errors.
Thanks!
