PLS HELP out removing an error from the Vxworks program

[kingsden]

i am using a program to run a round robin scheduling as soon as a counter gets to 0;

If i am initially giving the count value as 0 i do not get any prob and the round robin function works......

but when i give the count value as 3 or 4 the taskspawn for the round robin function does nt execute...... pls help me out.....demo pending in 5 hrs....no time

here's the code

#include "vxWorks.h"
#include "logLib.h"
#include "wdLib.h"
#include "sysLib.h"
