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.

rmf

RMF(1)								     [nmh-1.5]								    RMF(1)

NAME

       rmf - remove an nmh folder

SYNOPSIS

       rmf [+folder] [-interactive | -nointeractive] [-version] [-help]

DESCRIPTION

       Rmf removes all of the messages (files) within the specified (or default) folder, and then removes the folder (directory) itself.

       If  there  are  any  files  within the folder which are not a part of nmh, they will not be removed, and an error will be produced.  If the
       folder is given explicitly or the -nointeractive option is given, then the folder will be removed  without  confirmation.   Otherwise,  the
       user  will be asked for confirmation.  If rmf can't find the current folder, for some reason, the folder to be removed defaults to `+inbox'
       (unless overridden by user's profile entry "Inbox") with confirmation.

       If the folder being removed is a subfolder, the parent folder will become the new current folder, and rmf will produce  a  message  telling
       the user this has happened.  This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list
       and returning to the current folder from which the list was extracted.

       If rmf s used on a read-only folder, it will delete all the (private) sequences (i.e., "atr-seq-folder" entries) for this folder from  your
       context without affecting the folder itself.

       Rmf irreversibly deletes messages that don't have other links, so use it with caution.

FILES

       $HOME/.mh_profile	  The user profile

PROFILE COMPONENTS

       Path:		    To determine the user's nmh directory
       Current-Folder:	    To find the default current folder
       Inbox:		    To find the default inbox

SEE ALSO

       rmm(1)

DEFAULTS

       `+folder' defaults to the current folder, usually with confirmation
       `-interactive' if +folder' not given, `-nointeractive' otherwise

CONTEXT

       Rmf  will  set the current folder to the parent folder if a subfolder is removed; or if the current folder is removed, it will make "inbox"
       current.  Otherwise, it doesn't change the current folder or message.

BUGS

       Although intuitively one would suspect that rmf works recursively, it does not.	Hence if you have a sub-folder within a folder,  in  order
       to rmf the parent, you must first rmf each of the children.
