DataInputStream --- random incorrect parsing...

Hi,
I am working on a small java client and server program pair which at
client side packetizes data (such as jpeg image file) and appends some
header info for each packetized packet. At the server side, the
packetized data is reassembled back into the original image.

At client side I am using DataOutputStrea m/BufferedOutputS tream:

DataOutputStrea m data_out = new DataOutputStrea m(
new BufferedOutputS tream(client_so cket.getOutputS tream()));
data_out.writeI nt(seq_Num); // part
data_out.writeL ong(time_stamp) ; // of
data_out.writeI nt(image_size); // header
data_out.writeI nt(length); // for each packetized data
data_out.write( data, 0, length); // Packetized Data


On the server side I read back packetized data back sent by client and
later reassemble it back to original image:

DataInputStream data_in = new DataInputStream (
new BufferedInputSt ream(connection _socket.getInpu tStream()));

for ( ; ; ) {
seq_num = data_in.readInt ();
time = data_in.readLon g();
size = data_in.readInt ();
dlength = data_in.readInt ();
System.out.prin tln(seq_num + ", " + time + ", " + size + ", "
+ dlength);

byte[] p_data = new byte[dlength];
rlen = data_in.read(p_ data, 0, dlength);

Here's my problem
=============== ==
When I read data back at the server side I get corrupted data when I
parse byte packetized data, that is data from DataInputStream data_in

Here's the output:

seq_num=1, time=1067733150 359, size=65366, dlength=1000
Received Packet No. 1 from Node A . . .
seq_num=2, time=1067733150 361, size=65366, dlength=1000

dlength=1480003 007
Exception in thread "main" java.lang.OutOf MemoryError

Any ideas what causes this error? Any help would be greatly appreciated...
