Was your create_socket program still running, and in READY state?

You can verify both by using the following XRL by hand (you need to
replace "fea" with the target name of your module):
libxipc/call_xrl finder://fea/common/0.1/get_status

If everything is normal you should see the following output:
status:u32=3&reason:txt=

FYI, the values for the static codes are listed in
libxorp/status_codes.h and the value for PROC_READY is 3.
