Hello all!,
Recently I installed a SL6.1 Cluster with 16 nodes, slurm resource manager,
etc.
I use Emacs to edit my files as do some of the researchers of my
investigation center.
One day I detected that some daemons hunged. I discovered that the kernel
was killing some processes because the system went out of memory. I couldn't
reproduce the error anymore, and the thing seemed to occurr on very random
times.
Since this day, I limited with limits.conf the user stack to 15Gb. (my
server has 16gb, and consumes normally no more than 1gb).
Today, when I was doing some tasks I could see what is causing the problem.
It's Emacs!. There seems to be a user that uses emacs and that does logout
from his session without exiting it. The access to the server is done by
ssh.
I will try to install the latest 23.3 version with .tar.gz package but I
like to use the Yum package if it's possible in order to keep the
installation as "clean as possible".
Should I report it to some place?
Thank you.
Felip.
Here there is the info. that I gathered:
