Top Forums Shell Programming and Scripting Segmentation Fault(Core Dump) Error Post 302442181 by mick_000 on Tuesday 3rd of August 2010 01:14:01 PM

Hi,

I didn't try running any debugger. I will just describe the problem in detail. I have some 20 odd xls files which has some data in it. The filesize is less than 600KB put together. I have an unix script that will iteratively pick one file at a time and then call a java pgm which will perform some operations n write a output text file.

Given below is the code snippet:

Code:
FILES="*"
for file in `ls $FILES`
do
java -Xms512m -Xmx512m -classpath "-jars" javaFile $file        --Line NO 4
done

am passing the filename to the java pgm for performing some operations. Out of the 20 odd files , till the 9th file the whole pgm runs perfectly after which for each file i am getting an error in Line No.4 saying "Segmentation Fault(Core Dump)". I am running this script in unix server.

I tried executing a script file tat takes an input file size of 30MB and tat generates an output file of same size. The execution went well and i got no segementation fault for this scenario.

But in the case of less file size am getting this error. Can someone suggest an idea?

Thanks in advance.

DESCRIPTION

       The JPackage Project has two primary goals:

	- To provide a coherent set of Java software packages for Linux, satisfying all quality requirements of other applications.

	- To establish an efficient and robust policy for Java software packaging and installation.
	 We  focus  on	free and open source software whenever possible. For convenience, we also provide non-free packages without the restricted
	 source code.

       Our RPMs are generic in that they should work on any RPM based Linux distribution (Mandriva, Red Hat, SuSE, others). Other packaging format
	 suggestions are welcome too.
