Can templates collide/overwrite other templates?
Posted: Tue Apr 02, 2019 6:50 pm
I am now running numerous HTTP/FTP services (7 total), plus uploading to 16 weather/webcam services, plus running 4-6 apps that request data using template.cgi. ALl these on my new TL-MR3020V3 MeteoBridge.
Load-wise, these seem to work reasonably well, with load averages between 0.4-0.6 most of the time. Memory utilization leaves 19360kB free.
However, from time to time, I will see failed transmits in the Live Data tab that display HTML/JSON that doesn't look appropriate - often 50-100 characters. Also, *SOMETIMES* one or more of my apps will (apparently) get garbage/unexpected data back from their template.cgi calls - most often at the top of the hour, and often for as long as 5 minutes after the hour (doing 60-second GETs of the template).
Also, the system log frequently reports `no template file "/var/run/meteohub/template" for doing write on socket 5551`, as you can see at the bottom of this snapshot:
From this, it would appear perhaps that `template.cgi` requests are persisted in a file, and perhaps even that they are all using the same exact file name.
Is it possible that this is the case, and that my templates are being unintentionally overwritten?
FWIW, some of the templates I am using takes 6-10 seconds to complete (timing from when I execute the GET to when I get back a response). I have shortened the templates as much as possible, but the problem appears to persist.
