[Openvas-discuss] OpenVAS "internal error", scans not completing

Remy van Elst Sun, 15 Dec 2013 22:46:58 -0800

Hello,

My OpenVAS setup fails to complete scans. The setup consists out of 1 master node and 2 scanner nodes. The two scanner nodes are running on external VPS servers. Once a scan is started, it works for a while, I can see related processes on the scanner node and the it stops and in the web interface shows as internal error.

Sometimes it just scans two targets, sometimes more, most of the time it fails before the first target is scanned.

Included are the logs for a sample scan which fails. The scan is of my own domain, https://raymii.org. The IP adresses configured in Greenbone are: 64.188.45.131, 69.197.183.203, 84.200.77.168, 151.236.14.35, 192.71.245.64, 198.211.118.121, 205.185.117.74, 205.185.124.11.
