How much memory does your machine run with? please run: export MONO_THREADS_PER_CPU=125 and then try again if it still crashes please paste the output of mono -V and lsb_release -a

please use the latets stable version of mono, the nightly is known to be buggy

LifeGold commented 7 years ago

@DevilStarfinder Another How to put you will not prompt?

DevilStarfinder commented 7 years ago

the crash you are experiencing is most likely due to your mono version the nightly is a higly unstable version of mono the last stable is Mono JIT compiler version 4.6.0 , so first of you are using a outdated version second a buggy one

run: sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade after that please run sudo do-release-upgrade and let it do its thing

Hi there,

The reason you are seeing this error is not one caused by Virtual Universe itself, rather it is actually caused by the memory being low on your server.

It should be noted that the Unity Desktop which is the default in the Ubuntu Desktop operating system takes up approximately 1/2 to 2/3 of your operating system's allocated memory. The temporary solution would be to just reboot the server.

When running a grid on Linux it is usually better to run the server version of Ubuntu, Debian, Arch, Fedora, openSUSE, etc. However if you need to use a desktop environment in Linux, then I would recommend either XUbuntu x64 because it uses the XFCE desktop environment which takes up less space and resources in the Ubuntu Dstribution Flavour. There is also Manjaro which Virtual Universe does in fact work on to and it is nice and fast. Debian also provides a desktop operating system environment as well which works similar to Ubuntu and is stable and fast.

Mono - We never encourage grid operators to use a nightly build of mono as this is known to cause problems which are not problems we would generally see. Always use the latest stable version of mono. The latest stable version is 4.6.0 it will work just fine with Virtual Universe.

While this is not a bug caused by Virtual Universe directly, I will leave this issue open in case this becomes a persistant problem for you. However I would also recommend upgrading Ubuntu if you plan to stay with Ubuntu.

Closing as this appears to be an issue with Mono not caused by Virtual Universe.

If problem persists then please by all means open a new issue.
