DAEMON NAME Either "license daemon" or the string from the DAEMON line that describes your daemon. In the case where a single copy of the daemon cannot handle all of the requested licenses, an optional "_" followed by a number indicates that this message comes from a forked daemon.
The "top-level" daemon detected one of its sub-daemon's death. In trying to restart the chain of sub-daemons, it was unable to get the file descriptors to set up the pipes to communicate. This is a fatal error, and the daemons must be restarted.
