Crash every 2~3 min linux 3.16 64bits

Jau

Hello,

I'm using Ubuntu 14.04 x86_64
kernel 3.16.0-31

RepetierHost is always crashing after 2₃ minutes.

Here is the output :

~/RepetierHost$ mono RepetierHost.exe
Rebuild object False
Stacktrace:

Native stacktrace:

Debug info from gdb:

Could not attach to process. If your uid matches the uid of the target

See this thread http://forum.repetier.com/discussion/397/rh-started-crashing-after-10-minutes#latest for a solution. In short downgrade kernel to 3.13.0-46 to undo incompatible kernel changes.

Maybe I have a better solution : upgrade mono from 3 to 4
It looks more stable on my system. I'll do some testes, but I'm not crashing right now.

add this ppa : ppa:inizan-yannick/mono

sudo add-apt-repository -y ppa:inizan-yannick/mono && sudo apt-get update && sudo apt-get upgrade -y

If you are using Ubuntu 14.04 :

add the ppa then :
sudo gedit /etc/apt/sources.list.d/inizan-yannick-mono-trusty.list

In the file you just opened, change "trusty" to "wily". The author forgot the "trusty" version of his packages, but the wily versions seem compatible.

deb http://ppa.launchpad.net/inizan-yannick/mono/ubuntu wily main
# deb-src http://ppa.launchpad.net/inizan-yannick/mono/ubuntu wily main

Then, don't forget to :
sudo apt-get update && sudo apt-get upgrade -y

You can also do it in the software center, inside the sources. Paste the ppa then edit it and change trusty to wily the same way.

another crash after some hours (longer) :
