System ulimit

# ulimit -a

ulimit is a shell builtin command used to show and set various restrictions on resource usage for a shell. Among the limitations that can be set you find, maximum file size, maximum core file size, maximum size of resident memory. Though the restrictions are shell-independent, the exact syntax depends on what shell you are running.

It’s a good practice to set some of these limitations to prevent for instance a faulty shell script to start unlimited copies of it self or to prevent users on the system to start processes that run forever.

Summary     : The GNU libc libraries.
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.
