stack overflow in DaemonNew callback event

Hi,

I am working with ndk  and I am trying to implemt semaphore_post in the callback function of

DaemonNew but when I add the semaphore_post the output window shows

ti.sysbios.knl.Task: line 334: E_stackOverflow: Task 0x8347e0 stack overflow.
xdc.runtime.Error.raise: terminating execution

and in ROV I don´t see any indication to task 0x8347e0.

I have configured daemon as follows

 hHello = DaemonNew( SOCK_DGRAM, 0, 11, printf_hello,
                       OS_TASKPRINORM, OS_TASKSTKHIGH, 0, 1 );

Someone could help me telling how to increase the stack pointer
size beyond OS_TASKSTKHIGH?

Thanks in advance.

Julian
