linux memory logging kernel sigkill
I’m testing some software+driver for it on linux, and the driver uses the get_user_pages() in its internal functions. At some point my driver receives ERESTARTSYS error (-512) from the get_user_pages(), and according to the kernel code it happens because “If we have a pending SIGKILL, don’t keep faulting pages and potentially allocating memory.” – it’s a comment from memory.c kernel file. So my question is, how can I see who sent this SIGKILL and why? I was trying to look in /var/log/kern.log fi

I just installed texlive2012 on the new distribution Mageia 3, as well as the libertine font .rpm packages. I have a problem with this code :\documentclass[10pt]{article}\usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage{libertine}\begin{document} This is my first LaTeX document on Mageia 3. \end{document}when I compile I get zero error, but no PDF is built.

linux x-windows cuda
I have been running Red Hat Enterprise Linux 6.1 on a system with a GTX 480. Recently I added a 3GB GTX 580, as my CUDA application requires more memory than I have on the 480. Due to space issues in the box, I had to place the 580 on the PCI-E bus closest to the CPU and move the 480 to the second slot.Now, when I run RHEL, X windows is running on the 580. What I would like to do is have the 480 run X windows so the full 3GB is available on the 580. I only have one monitor – it will only display

linux unix logging monitoring
In our current system, we are not effectively monitoring the logs for errors as most of the errors are not serious enough. I want to basically warn users on the important errors. I cannot touch the code, so I cannot change these messages type to fatal.So, I want to write scripts searching logs for the regex of the important error messages. Is there a opensource software package that does this?
