Assistance pls - pipe error: Too many open files in system
When I run a bash script in the customer system, it throws the warning and script exits

Exec '/root/sample.sh' @ hostname-- OK
(warn) /root/sample.sh: pipe error: Too many open files in system
/root/sample.sh: n + : syntax error: operand expected (error token is " ")

Exec '/root/sample.sh' @ hostname -- OK
(warn) /root/sample.sh: fork: Cannot allocate memory
/root/sample.sh: n + : syntax error: operand expected (error token is " ")

In the script - variable n is used in this below statement.Where as variable n is not initialised to zero.

Code:
 n=$(( n + $(find $j -type f | wc -l) ))

whether the variables need to be explicity initialized to zero beforing using them.

does this cause below warnings Too many open files in system / cannot allocate memory Smilie

Please anyone clarify me

initscript

INITSCRIPT(5)						Linux System Administrator's Manual					     INITSCRIPT(5)

NAME

       initscript - script that executes inittab commands.

SYNOPSIS

       /bin/sh /etc/initscript id runlevels action process

DESCRIPTION

       When  the  shell  script /etc/initscript is present, init will use it to execute the commands from inittab.  This script can be used to set
       things like ulimit and umask default values for every process.

EXAMPLES

       This is a sample initscript, which might be installed on your system as /etc/initscript.sample.

	      #
	      # initscript   Executed by init(8) for every program it
	      # 	     wants to spawn like this:
	      #
	      # 	     /bin/sh /etc/initscript <id> <level> <action> <process>
	      #

		# Set umask to safe level, and enable core dumps.
		umask 022
		ulimit -c 2097151
		PATH=/bin:/sbin:/usr/bin:/usr/sbin
		export PATH

		# Increase the hard filedescriptor limit for all processes
		# to 8192.  The soft limit is still 1024, but any unpriviliged
		# process can increase it's soft limit up to the hardlimit
		# with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).
		ulimit -Hn 8192

		# Execute the program.
		eval exec "$4"

FILES

       /etc/inittab, /etc/initscript.
