Hi,

I am downloading an Vxworks image of 4 MB on my Power PC
architecture. Initially the stack size of the downloading task
( "txbdService ") is of 4096 bytes, which is lower. After downloading
1.5 MB, downloading will get failed. But if i'll increase the stack
size from 4096 to 16384. I am able to download the 4 MB of Image.

On what basis the task stack size has to be increased ? I mean, what
will happen if i'll keep the stack size large enough and how it will
effect the system ? and Vice versa.
