What version of nxagent do you have installed on the server?

There will be a 3.5.99.25 release in the next days (hopefully) which
fixes some crashes. If you do not want to wait you can compile your
own version from this tree: https://github.com/ArcticaProject/nx-libs
(Instructions in the README.md)
