I'm not communicating.

Example:
If you have called setrlimit and set the max file size down to a number, say 100000, then the kernel will send SIGXFSZ to your process. When your file size hits the limit. You then call setrlimit and bump up the value.

If you do not call setrlimit, then the kernel will send SIGXFSZ when your process hits the system-wide value (or the per-process-defined value) for max file size.

The fact that your system seems to support 64-bit file size means:
Your default system max file size is probably more than 2147483647.
It is not clear to me how you arrived at 2147483647.
Did you set that value with setrlimit?
If file size shows "unlimited" it means that it uses the system-wide setting.
"unlimited" does not mean unlimited or infinite. It just means that the process limit is the same as the system.

Try playing with setrlimit on very small files and see what happens. Then you can create a model that will work on really big files.

ns_rand(3aolserver)					    AOLserver Built-In Commands 				       ns_rand(3aolserver)

__________________________________________________________________________________________________________________________________________________

NAME

       ns_rand - commands

SYNOPSIS

       ns_rand ?max?
_________________________________________________________________

DESCRIPTION

       ns_rand	generates  a  cryptographically-secure random number.  If max is not specified, the random number is a floating-point value n such
       that 0.0 <= n < 1.0.

       If max is specified, it must be a positive integer between 0 and 2147483647.  The return value is an integer value such that 0 <= n <= (max
       - 1).

       Internally  ns_rand is implemented with the drand48(3) and lrand48(3) standard library functions.  An internal random seed is generated the
       first time ns_rand is called after the server starts.

EXAMPLES

	nscp> ns_rand
	0.39938485692

	nscp> ns_rand 10
	7

SEE ALSO
