lua pro question about io.open freezing
Posted: Sunday 19 January 2025 10:13
Hi
i recently experience freezing of io.open after some time ( > 60 minutes). My system setup :
I have a lot of data gathered thrue windows schedular (curl and headless chrome canary) and stored in a text file. ( about 70 files)
I do this by schedular to avoid freezing domoticz when collecting the data from the web. Of course there are a few running low frequent like once an houre and some every minute. (think about tplink p110 smartplug for example, i use the api outside of domoticz with a python script)
The contents of the text files are read by plain lua -see below- (no dzevents and working from the script dir in domoticz)
I make sure to have it run all at different times to avoid having to much files open for the OS (win10 pro)
System resources are constantly below 80% on an intel core i7- 2620M
i runn a taskkill on schedular every hour to kill ghosts from python and cmd ( using batch files) witch i seem not to can avoid ... i dont understand why python and cmd ghosts exist as the scripts seem to finish correctly
The script function i am using to read the data :
Question:
At this moment i restart domoticz every hour just to keep it working, but it causes a short freeze and thats annoing. I kill the domoticz process by ID and nssm is picking it up very fast to start domoticz again.

Code: Select all
function readAll(filenaam)
ok=fileexists(filenaam)
if ok==true then
local f = io.open(filenaam, "rb")
content = f:read("*all")
f:close()
return content
else
print(filenaam.." error file does not exist")
return "error file does not exist"
end
endAt this moment i restart domoticz every hour just to keep it working, but it causes a short freeze and thats annoing. I kill the domoticz process by ID and nssm is picking it up very fast to start domoticz again.
- What could be causing io.open to get unresponsive ?
and how to avoid the freeze ?
Is there a smarter way to gather the data from the text files other than io.open ?
