Cumulus hangs shortly after midnight...

The graphs window wasn't really designed to be left open permanently. There's no particular reason that it shouldn't work, but it looks like it does cause some kind of problem. So I would think it may well happen again.

One thing I do notice in the diags files is that you have Cumulus and your station set to a different log intervals (1 minute in Cumulus and 10 minutes in the station). This causes the Davis feature to be activated where the stations sends the entire contents of the logger every time Cumulus starts:

09/09/2011 15:52:44.984 : VP2: DownloadData_V = 2559
09/09/2011 15:52:44.984 : VP2: GetNumberOfArchiveRecords_V = 2559
09/09/2011 15:52:44.984 : VP2: Number of history records = 2559
09/09/2011 15:52:45.000 : Logger entry zero: Y = 2011, M = 8, D = 22, H = 21, M = 10
09/09/2011 15:52:45.000 : VP2: Earliest timestamp 22/08/2011 21:10:00
09/09/2011 15:52:45.000 : VP2: Earliest timestamp is earlier than requested
09/09/2011 15:52:45.000 : VP2: Find first entry after 09/09/2011 15:47:00
09/09/2011 15:52:45.000 : VP2: Checking logger entry 0 Y = 2011, M = 8, D = 22 H = 21, M = 10
09/09/2011 15:52:45.000 : VP2: New earliest timestamp 22/08/2011 21:10:00
09/09/2011 15:52:45.000 : VP2: Checking logger entry 1 Y = 2011, M = 8, D = 22 H = 21, M = 20

You may not consider this to be a problem; Cumulus tries to cope, but it means that the start up takes much longer than it should. You may want to set both to the same interval.

I reset the archive interval on the logger to 10 instead of 1 so it holds about 17 days or so. That way every couple of weeks I can stop Cumulus and run WL. If this is only a problem that slows the start up and does not effect the day to day running of Cumulus then I can live with that.

Yes, the only effect should be a slow start up, it should manage to weed out the entries that it needs. I should really get around to writing the code to stop this being an issue in the first place!

Just wanted to say that since my last post over a month ago, Cumulus has been running perfectly with the graphs open side by side with the absence of VVP. V happy.

Is there no other way other than VVP to run Cumulus and WL together? I've really got into this weather thing in the past year and have been looking at WXSIM but it needs data from WL to work.

Not that I'm aware of.
