root cause
java.lang.OutOfMemoryError
It happens When the corresponding request returns more than 20000-30000
rows from the database, not every time
but surely if more request run parallely
>From the 20000-30000 rows I am making the same number of the following
objects from this class
class{
public int humanId=-1;
public String humanDescription="";
public String swissProtId="";
public String swissProtName="";
public String function="";
public String subcellularLocation ="";

public String pathway ="";
public double mitoProt =-1;
public int mitoLocal=-1;
