Hi All,
In “My Alerts” i get lots of “Lighttpd failure” system errors - I click on “view Notification” and there is no data or detail?
Something is obviously not right here but any ideas whet it might be?
Thank you.
Lighthttpd is the webserver that runs on your Vera.
I’d recommend a complete restart(powercycle) of Vera.
Hi Z-Waver,
Thank you for the reply.
The unit is tucked away but I do reboot via a scene with Lua code each night - this would be the same as total power down and reboot right? (e.g pulling the cable)
I will try that later today (cable pull) but think this will not resolve the problem as it has been power cycled like you state recently and logs show the error going back for some weeks now.
any other way to trouble shoot that you could think of?
Are the times correlated with things you are doing ? Like rebooting ?
Just had a look and no correlation is obvious so no i don’t think so. i have around 15 of these a day and some are as close at 15 minutes apart and some 5/6 hours apart - so seems random, sure it isn’t, but seems that way?
I’m getting the same… anyone any ideas?
Yes currently I see this as well on my Edge usually one time a day (sometimes two or three),
I will see the Ligttpd failure, it will happen every thirty seconds for about 10 minutes them finally Vera will initiate a Reboot:CheckLUDiff which fixes the issue. I have seen it in the morning, evening, etc.
I can’t find any strong correlation to any scenes running on my vera that is triggering it. Sometime it is occurring when no-one is home and the house is totally quiet with no automation running and no other alerts or anything.
The only thing that is different on my system is that I added a HSM200 a while back so wonder if it is the culprit but really have no idea.
As stated previously, Lighttpd is the Vera webserver. It provides the web interface, GUI and access for smartphone/tablet apps. Z-Wave devices and scenes will almost certainly not affect it. Things that might affect it(but shouldn’t really) would be:
PC/Browser left connected all the time.
Network scanning/probing by other devices.
Smartphone/tablet apps making requests or refresh updates.
If you can’t put your finger on the likely cause, I’d recommend that you contact Vera support.
Hmm, don’t think I have any of those situations going on (no network sniffing, no browser left open all the time… no app). Like I said most of the behavior on my machine is occurring when no-one is home and nothing is going on. I am the only one in the family that does anything with the website or apps.
I do have Vera support looking at it, but they are being super slow (take 4-5 days to ask me a question then go away for another 4-5 days, etc).
How has your router setup the IP address for Vera ?
Is it possible the IP address is changing ?
I fixed that one on Saturday, by making sure the Vera had a reserved Address on the router so the address has been stable but still seeing this issue. Beyond that I am stumped problem started before the latest firmware upgrade, but is definitely recent, to the last 4 weeks or so.
See if you have an option to extend the reservation time!
I permanently reserved the IP address the Vera is using… Aka it is using a static IP address, so that isn’t the problem.
[quote=“shallowearth, post:13, topic:181333”]I permanently reserved the IP address the Vera is using…[/quote]The permanent reservation isn’t the same as the lease time that Richard was referring to. Lease times still apply, even with reservations and will cause Vera to re-request/verify/refresh the reserved IP at half the lease time. e.g. Lease time 24 hours, Vera refreshes the lease every 12 hours. This is how DHCP works.
Aka it is using a static IP address, so that isn't the problem.You don't know that. I think that you are probably right, but Richard may have something in mind that neither of us have experienced yet.

I have this same problem as well. Contacted support, they said they couldn’t see it in the logs asked me to log to usb drive as it holds more log data…
OK, yesterday it went into a crash loop at 10pm, 4am and 11am (particularly bad day… some days it doesn’t happen at all or only once).
I will see if I can fiddle somemore with the DHCP reservation but this still feels wrong to me. The problem only started happening about a month ago and was stable before then for 4 or more month and that was when I didn’t even have a reserved IP address for the Vera, so doesn’t feel like the culprit to me.
Just for giggles, go to the network setting and reset to default settings. Of course, this may not resolve the issues, but in doing so, you should be able to rule out Vera network configuration if it re-occurs. Process of elimination to try and narrow down the root cause.
OK, did a network reset (though I have never touch any settings on the Vera Networking tab). No affect, if anything made the problem worse as last night the Vera went through 4 failure cycles back to back from 2:00am-3:00am instead of the usual 1 (aka 10 minutes of lighttpd failuers ever 30 seconds, reboot, then 3 minutes later another 10 minutes of lighttpd failures, etc).
Will see what I can do with my home routers lease time to see if that is the issue.
As z-waver mentioned earlier, this is the internal Vera web server. It is highly unlikely the crash is related to external router but a factory reset will default all of the Backend configuration of your Vera, this is what the reset network configuration is intended to do to a lesser degree.
The would suggest the options I would use either contact support or full factory reset and then restore.
Support claims they are looking at it, but has been 2 weeks now, and I have pinged them a few times, but never gotten a response after a short… ping against again if you are still seeing a problem.
I did double check the lease time on the router and it set to 1 week for ipv4 addresses. So with a reserved address if the lease time is the culprit you would expect the error to only be happening once or twice a week or so.
Now that good news is that after I did a network reset, after the flurry of errors later that day, it has now been error free for a few days… so maybe that was enough to shake it out of its funk. If not, I will start pinging support again for some help.
