error: handle abandoned timeout (status=4)

[ropske]

Hi,

anyone knows what this means?
I get this often in my domoticz log file:

2017-12-14 10:20:57.409 ::ffff:192.168.1.199 -> handle abandoned timeout (status=4)

Are you using IPv6?

hi SweetPants,

no i'm not using that.

The error is coming from the webserver (webserver/connection.cpp). The host IP address (::ffff:192.168.1.199) looks a litlle weird to me. It get's a timeout reading the connection (status (4) = READING) as far as i can see, but i'm not an expert on C++

Hi,

I have the exact massage in my log. It appears every time exactly 20 minutes after initiating a backup by a backup script.

..It appears every time exactly 20 minutes after initiating a backup by a backup script.

It looks like your network or a particular network interface is very busy causing the TCP layer to timeout. Could it be caused by a massive data transfer from the backup ?
Read this article for some background and on how to adjust timeout settings.
