The parameters you passed to dapl_ep_connect don't look good:

dapl_ep_connect (0x8057218, 
{4294967280.4294967295.4294967295.4294967295}, 4A275800, 0, -1, (nil), 
0, 0)

The second argument should be the IP address you want to connect to. 
The address doesn't look good. Can you verify that you are passing 
uDAPL a good address?

I'll look over our code to see if there is a bug in our debug 
statement. We are printing out the 8-bit octets of the IP address as 
unsigned integer values. I can't explain why octet 1 is 0xFFFFFFF0 and 
octets 2,3, and 4 are 0xFFFFFFFF. 

Also your private data size is -1. I would change that to 0, but this 
isn't the problem.
