tl;dr: After configuring my WeeWx 5.4 instance to generate reports,
updates to Meteotemplate are behaving very strangely, and running a
report takes forever (three days and counting).
I'm running WeeWx 5.4.0, installed via apt on Debian 13.5 in a virtual
machine provisioned with 4 cores of a Xeon E-2224 and 4 GB RAM. It's
connected to a Vantage Pro 2 console via USB.
As of about a week ago, everything was working fine. WeeWx was logging
data to Weather Underground, WeatherCloud, PWSWeather, and my
Meteotemplate installation on a remote VPS. It was storing its data in
a MySQL database, also on that remote VPS. The archive table goes back
to 2015, about 5M rows. Meteotemplate gave a nice, responsive web page,
with live updates from my weather station, and while it wasn't
well-maintained, it did the job.
About a week ago, I learned that Meteotemplate would be discontinued
entirely, the domain registration would lapse, the forum would go away,
and there'd be no support resources left. As a result, I decided to
look into using WeeWx to generate the web display. I installed the New
Belchertown and Me.teo skins, and that's where I started having trouble.
I first noticed that generating the reports (specifically, the Me.teo
report) was taking a very long time. Surely part of that would result
from having to build daily JSON for every day of 11 years, but it still
seemed that running for days and still not finishing wasn't right. And
I figured that having the database on a remote host would slow it down,
so I stopped WeeWx, downloaded a database dump from that server, and
recreated the weewx database locally. I then updated weewx.conf to
connect to localhost and restarted. And the result is, well, no change
that I can tell. After restarting WeeWx, I did `weectl report run
Me.teo`, and that's been running for three days so far--and the last
daily .json file it's created is for 2016-06-14, over 10 years ago. I'll
return to this issue in a moment.
The second issue I'm noticing is that updates are being pushed to
Meteotemplate--and only to Meteotemplate--very badly out of order. See
this snippet from the log:

Four updates sent at the same time, for four different times on three
different days. I don't see any errors or other indications as to why
this is happening.
I'm suspecting a database-related problem, though I'm not sure why it
would be happening. The VM stats for the system running WeeWx are
showing an average of about 50% CPU usage over the last day, and htop is
showing over a dozen mariadb processes, with the first eight or so each
listed as consuming about 20% CPU. RAM doesn't seem to be a problem;
the system's pretty steady at 1.5 GB used.
The Meteotemplate logging issue made me suspect I somehow had another
weewx process running, but `ps -aux | grep weewx` indicates that isn't
the case--the only output (other than the grep itself) is the main weewx
process, and the weectl report run one.
Here are logs after restarting weewx:
