Hi,

I have a question with which i am really confused. In /etc/security/limits.conf , there are many parameters that i can set. But among them 'data' and 'fsize' are also two parameters which i cannot differentiate.

What is the difference between 'data' and 'fsize'..???

Code:

      RLIMIT_DATA
              The  maximum  size  of  the  process's data segment (initialized data, uninitialized data, and heap).  This limit affects
              calls to brk(2) and sbrk(2), which fail with the error ENOMEM upon encountering the soft limit of this resource.

       RLIMIT_FSIZE
              The maximum size of files that the process may create.  Attempts to extend a file beyond this limit result in delivery of
              a  SIGXFSZ  signal.   By default, this signal terminates a process, but a process can catch this signal instead, in which
              case the relevant system call (e.g., write(2), truncate(2)) fails with the error EFBIG.
