Encoder Limit

[agough]

Is there an encoder limit?
I ask because when we build our program with 5 encoders used throughout it builds fine and it downloads but when we start it up our program won't run and tells us:
"Cannot allocate any more ports" check Resource.cpp line 61
We found nothing in Resource.cpp that is relevant.This is function/line it tells us to check(_=Space):

UINT32 Resource::Allocate()
{
____for (UNIT32 i=0; i < m_size; i++
____{
__________if ( ! m_isAllocated[i])
__________{
__________m_isAllocated[i] = true;
__________return i;
__________} <-This is line 61
____}
____wpi_fatal(NoAvailablePorts);
____return 0;
}

If we comment out at least one encoder object creator and pointer(and it doesn't matter which one of the five we comment out) then the error doesn't show and everything else works.
