too many open files

HI I am trying to run the following script for 317 files (*.m) and I get this error :
awk: xfile.m makes too many open files
what's the solution pls ?

Code:

$ cat ocstr2.awk

# If the code contains @"LBL_....", replace it with C_LBL_... and
# remember the labels for later.
match($0, /@"LBL_[0-9]*\"/) {
        S=$0; P=""

        do        # Loop until there's nothing left in the right half
        {
                A[L=substr(S, RSTART+2, RLENGTH-3)]++; # Remember label
                P=P substr(S, 1, RSTART-1) "C_" L;
                S=substr(S, RSTART+RLENGTH);
        }
        while(match(S, /@"LBL_[0-9]*\"/)); # Keep hunting for more labels

        $0=P S; # Update the line to be printed
}

# If we are given file.pm, print into file.m
{       O=FILENAME;
        sub(/[.]m$/, ".pm", O);
        print > O;      }

END {
        for(L in A) printf("NSString *const C_%s = @\"%s\";\n", L, L);
}

atf-sh

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME

     atf-sh [-s shell] -- interpreter for shell-based test programs

SYNOPSIS

     atf-sh script

DESCRIPTION

     atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.

     atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL.  atf-sh executes the inter-
     preter, loads the atf-sh(3) library and then runs the script.  You must consider atf-sh to be a POSIX shell by default and thus should not
     use any non-standard extensions.

     The following options are available:

     -s shell	  Specifies the shell to use instead of the value provided by ATF_SHELL.

ENVIRONMENT

     ATF_LIBEXECDIR    Overrides the builtin directory where atf-sh is located.  Should not be overridden other than for testing purposes.
     ATF_PKGDATADIR    Overrides the builtin directory where libatf-sh.subr is located.  Should not be overridden other than for testing purposes.
     ATF_SHELL	       Path to the system shell to be used in the generated scripts.  Scripts must not rely on this variable being set to select a
		       specific interpreter.

EXAMPLES

     Scripts using atf-sh(3) should start with:

	   #! /usr/bin/env atf-sh

     Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh.  Instead, you have to hardcode
     the path to atf-sh in the script and then use the -s option afterwards as a single parameter:

	   #! /path/to/bin/atf-sh -s/bin/bash

ENVIRONMENT

     ATF_SHELL	  Path to the system shell to be used in the generated scripts.
