#21 0x00007fff8f57b086 in gethostbyname ()
#22 0x000000010b75571c in my_hostdomain () at hostpid.c:39

Where the code is:

                hent = gethostbyname(my_hostname);

The gethostbyname() call is used to figure out the current system's domain. Why it would be hanging there, I don't really know. That call anyway isn't fully required, you could just replace it with "hent = NULL;"
