dzVents crashing Domoticz ?

[jeanclic]

Hello everyone,

I am facing an issue since I use dzVents (4 scripts so far, 20 in "standard" lua). From 2 to 4-5 times a day, I got this in the logs :

2017-08-17 07:22:13.708 Error: EventSystem: Warning!, lua script /home/pi/domoticz/scripts/dzVents/runtime/dzVents.lua has been running for more than 10 seconds

2017-08-17 07:24:30.116 Error: EventSystem thread seems to have ended unexpectedly

Then I of course need to restart the domoticz service (I have a bash script doing that for me).

Did I missed something ? -> my Logging level is on "Error + forced messages".
As my signature say, I am on 3.8153, so my dzVents version is 2.2.0.

EDIT : see the Last Domoticz starts I have recorded :

Maybe try disabling the dzvents scripts and see if it still crashes?
Then enable them one by one, and determine which one is causing the problem.

Thank you for the idea, I just disabled the last script I wrote. I will come back here in a few to update the status of my issue

[dannybloe]

Not sure what you are doing but if a script is running for more than 10 seconds then there's surely something wrong with your script.

[tlpeter]

Not always as i have seen this happen sometimes while it normally worked fine.
But i have seen this some beta versions ago and did not occur lately.

[jeanclic]

As promised, I come back here to say where I am : since I disabled my script Yesterday, no more Dz crash : my Dz is up for more than 24 hours now.

Here you find my script, in case of someone has time to look at it and point me some bugs out (sorry, the comments are in french, but I think its still understandable) :

    return tostring(string.sub(path, 1, string.len(path)-4))
end
local function checkSecurity(oDz, oDevice, iLevel)
    if devicesToCheck[oDevice.name] == iLevel then
        if oDevice.state == 'Open' or oDevice.state == 'On' then
            oDz.notify('Alarme intrusion', 'La maison est en mode '..oDz.security..' et '..oDevice.name..' est '..oDevice.state..'. Il y a probablement une intrusion.', oDz.PRIORITY_EMERGENCY)
            oDz.log(oDevice.name..' '..oDevice.state, oDz.LOG_DEBUG)
        end
    end
end
return {
	active = true,
	on = {
	    devices = {
    	    'Fenêtre*',
    	    'Porte*',
    	    --'PIR_Rdc'
		}
	},
	logging = {
        level = Debug,
        marker = '['..file()..']'
    },

	    iSecOnDelay = tonumber(domoticz.helpers.os_capture("curl -s 'http://127.0.0.1:8080/json.htm?type=settings' | jq -r '.SecOnDelay'"))
	    if device ~= nil then
            if domoticz.devices(SecPanel).lastUpdate.secondsAgo > iSecOnDelay then
                if domoticz.security == domoticz.SECURITY_DISARMED then
        	        domoticz.log('Statut Alarme : "Désarmée" depuis le '..domoticz.devices(SecPanel).lastUpdate.raw, domoticz.LOG_DEBUG)
                elseif  domoticz.security == domoticz.SECURITY_ARMEDHOME then
         	        domoticz.log('Statut Alarme : "Armement en présence" depuis le '..domoticz.devices(SecPanel).lastUpdate.raw, domoticz.LOG_DEBUG)
                    checkSecurity(domoticz, device, 1)
                elseif  domoticz.security == domoticz.SECURITY_ARMEDAWAY then
         	        domoticz.log('Statut Alarme : "Armement en absence" depuis le '..domoticz.devices(SecPanel).lastUpdate.raw, domoticz.LOG_DEBUG)
                    checkSecurity(domoticz, device, 2)
                end
            end
        else
            domoticz.log('Ce script doit être appelé uniquement sur "devices"', domoticz.LOG_ERROR)
        end
	end
}

I created the "file()" function yesterday, and I just reactivated this script to see if with this function, I can spare the filename calculation at each call of this script.

[dannybloe]

The http call is probably the culprit here as it may take long or worse. Better not do that.

[jeanclic]

Yes I think that too but I did not find any alternative to that... I don't think there is a 'domoticz.settings(«SecOnDelay»).value' available in dzVents... am I right ?
The obvious alternative is to put some parameter inside this script but I don't like dobbling parameters if I can avoid it...

[jeanclic]

So, defined a variable named "SecOnDelay", and I update it one time per day via a bash script containing those lines :

Code: Select all

SecDelay=`curl -s "http://127.0.0.1:8080/json.htm?type=settings" | jq -r '.SecOnDelay'`
curl -s "http://127.0.0.1:8080/json.htm?type=command&param=updateuservariable&vname=SecOnDelay&vtype=0&vvalue=$SecDelay" > /dev/null

And I changed my dzVents scripts by this one :

Code: Select all

        else
            domoticz.log('Ce script doit être appelé uniquement sur "devices"', domoticz.LOG_ERROR)
        end

}

I will see in the next days if its crashing again

[dannybloe]

You can also create a global persistent variable in global_data and create a script that only runs once a day and only does the request if the var is empty. Quite simple with dzVents.

Hi,

I think its a general problem as I was playing with DzVents and noted the same problem:
Error: EventSystem: Warning!, lua script ...domoticz/scripts/dzVents/runtime/dzVents.lua has been running for more than 10 seconds

Removing all dzVents scripts doesn't resolve this issue. It seems that this script is embedded after being used?? as
dzVents: All based event fired, keeps being logged..

Is there a solution to disable dzVents to check if this indeed related to the system crash?

Thanks,

Mark
