OutOfMemory Error due to unknown reasons

Question

HI ALL
In my application iam reading an audio File nearly of size 55, 100MB etc and the graphical display
of the audio file is shown.Recently we have included the feature of opening multiple audio files
using JInternal Frames. Now when i try to open the above said size file OutOfMemory Error is thrown.
Iam not able to find the reason as iam cooly able to open the file in single JFrame.
I even tried to create only single JInternalFrame to open the 100MB file only but even then OutOfMemory Error is thrown
The code for drawing the graph is:
double y_new;
byte[] sampleByte = new byte[1];
DataOutputStream dos = new DataOutputStream(new BufferedOutputStream(new FileOutputStream("linesTop.txt"),1000));
for( int j=0 ;j <length of file; j++)
audioInputStream.read(sampleByte);
y_new = (h1*sampleByte/256); //some calculation
dos.writeDouble(y_new);
dos.flush();
dos.close();
I thought to increase the Ram Size with command java -Xxm.... but i heard that the appl will become
slow and has many draw backs so i want display the graph without increasing the heap size.
Any Ideas /Suggesstions will be greatfully thanked.
Wating for an idea...............

Sorry - part of it is I'm not sure what logs to post. I've tried downgrading the kernel from 2.6.39 to 2.6.38 (seemed to start after the kernel upgrade), switching from Wicd to NetworkManager (couldn't even get NetworkManager to work) and looked through the various logs in /var/log, and none of them seem to have any errors - heck, the pm-suspend log claims that the suspends are a success. If I run pm-suspend in a terminal, it seems to do nothing and if I kill it it does a wonky suspend that pretty much renders the computer unuseable afterwards. (With a nice graphcal distortion.)
Kernel logs don't report errors either, and the problems occur if I suspend from the XFCE menu as well.
Also, my wireless card shows up as: Atheros Communications Inc. AR9285 Wireless Network Adapter. I also tried removing the logmein-hamachi daemon I installed recently.
