Sometimes SAFNWC won't start with the normal SAFNWC command. This generally happens when it has been overloaded and crashed. In this case you may need to look for a stray process and kill it prior to restarting the program. To do this run the following.

ipcs -q

You will then see

------ Message Queues --------

key        msqid      owner      perms      used-bytes   messages    

0x771103e9 1277952    ncas-sat   666        0            0       

This indicates there is a stuck process in a queue with the id of 1277952

to kill this run the following command with the msqid that the last command lists.

ipcrm msg 1277952 

You should now be able to restart the program in the normal way.
