java memory leak problem

[허영]

my team developed a java application using socket for ftp function.
and we found it has severe memory leak after monitoring HPjtune and HPjmeter.

still trying to find which part is wrong but the source code looked alright.

most of the cases, we usually don't think about memory leak about java, because garbage-collector does manage memory and there's no way to remove instances in java source code(like 'delete ..' in C++).

i want to know which case brings memory leak when we writes java source code.

thank you,

Have a read of some of the stuff returned by:

A simple start is to first concentrate on areas of that that are repeatetly executed.
