using java 5.4 and web application Tomcat server 6 we run web
application in AIX.

it has 8 GB hard disk

aplication stops frequently by throwing exception out of memory when
processing some 10000 records.[ this happen only at the time of
processing huge records]

and create log files in tomcat bin directory.

we try so many ways

by increasing heap size for java virtual machine.

in coding we have set null to string variables in finally block

we shift to use stringbuffer in program.

but it not work out.


where we have made mistake?
how we have to trouble shoot this problem?
