Sizes are in multiples of 512 byte blocks, CPU time is in seconds
fsize      - soft file size in blocks
core       - soft core file size in blocks
cpu        - soft per process CPU time limit in seconds
data       - soft data segment size in blocks
stack      - soft stack segment size in blocks
rss        - soft real memory usage in blocks
nofiles    - soft file descriptor limit
fsize_hard - hard file size in blocks
core_hard  - hard core file size in blocks
cpu_hard   - hard per process CPU time limit in seconds
data_hard  - hard data segment size in blocks
stack_hard - hard stack segment size in blocks
rss_hard   - hard real memory usage in blocks
nofiles_hard - hard file descriptor limit
The following table contains the default hard values if the
hard values are not explicitly defined:
  Attribute        Value
  ==========    ============
  fsize_hard    set to fsize
  cpu_hard      set to cpu
  core_hard         -1
  data_hard         -1
  stack_hard      8388608
  rss_hard          -1
  nofiles_hard      -1
NOTE:  A value of -1 implies "unlimited"

        core = 2097151
        cpu = -1
