Problems with L2cap socket

[y2kstar]

Hi all,
When I Sending data continuously and last for 30 or 40 minutes, I received 3 error codes -10, -39 or -36 and the L2CAP connection drop.

what's wrong with my program?

/////////////////////////////////
SendData
{
...
iL2dapSocket.Write(iAvdtpMediaPacket,iStatus);
SetActive();
}

RunL()
{

if( (iStatus.Int() != KErrNone) )
{
...// here I receive -10,-39 or -36
}
...
}

according to this:

they are: Underflow, Interrupted, and disconnected.

is the iAvdtpMediaPacket, a class member variable ? so it will stay valid in all ways, untill the RunL is called ?

After checking my engine's machine state, I found Underflow comed from another function and I fixed it.
Now the L2CAP transmission persists 1 hour or above, but -39(KErrAbort) or -36(Disconnected) still come in the end. Would anybody give me a hint?
