## Path System/Limits
## Description: Set single process limits (memory, CPU, core ...)
## Command: killall mingetty
#
# Both hard and soft limits may be set. Soft limits are enough if you
# trust the users. Then, the soft limits may protect your machine
# against suffering too much from an application leaking memory.
# If you don't trust your users, you may use hard limits to prevent
# the amount of harm they can do to the machine. Note that this is
# only partially effective: Memory limits are per process, not per
# user.
# A setting of 0 will skip the adjustment of the particular limit
# (except for core file sizes), thus the default will remain in
# place, which is "unlimited" for most limits. If a value is unset,
# no adjustment will be made either.
# The memory sizes are percentages, the other values are absolute
# numbers.
# Note that the limits only get effective after a session is
# restarted by init. Thus exiting mingetty (^D on console login)
# or changing runlevel to 3 and back to 5 for xdm is needed.
# Rebooting helps as well, of course.
#
## Type: integer(0:99)
## Default: 0
#
# Limit the amount of virtual memory a single process may allocate.
# Hard limit: Can not be increased by non-root.
# This value corresponds to ulimit -Hv
# Parameter is in percent of virtual (phys+swap) memory, 0 means
# no adjustment (unlimited).
#
HARDVIRTUALLIMIT=0
## Type: integer(0:99)
## Default: 80
#
# Limit the amount of virtual memory a single process may allocate.
# Soft limit: Can be increased by non-root up to the hard limit.
# This value corresponds to ulimit -Sv
# Parameter is in percent of virtual (phys+swap) memory, 0 means
# no adjustment (unlimited).
#

## Type: integer(0:99)
## Default: 0
#
# Limit the amount of resident memory a single process may occupy.
# The process virtual memory can grow larger than this limit, but
# it can not get more resident memory.
# Hard limit: Can not be increased by non-root.

# (unlimited).

# of multithreaded programs and should thus better not be set.
# Hard limit: Can not be increased by non-root.
# This value corresponds to ulimit -Hs
# Parameter is in percent of physical memory, 0 means no adjustment
# (unlimited).
#

#
# Limit the size of the stack that a single process may allocate.
# Normally, it should be enough to limit virtual and resident size.
# Note that with NPTL, the stack limit determines the stack SIZE
# of multithreaded programs and should thus better not be set.
# Soft limit: Can be increased by non-root up to the hard limit.
# This value corresponds to ulimit -Ss
# Parameter is in percent of physical memory, 0 means no adjustment
# (unlimited).
#

## Type: integer(0:99)
## Default: 0
#
# Limit the size of the data segment that a single process may allocate.
