A mis-use of L{IUNIXTransport.sendFileDescriptor} caused the connection to
be closed.
Each file descriptor sent using C{sendFileDescriptor} must be associated
with at least one byte sent using L{ITransport.write}. If at any point
fewer bytes have been written than file descriptors have been sent, the
connection is closed with this exception.

Emitted when L{IReactorProcess.spawnProcess} is called in a way which may
result in termination of the created child process not being reported.
Deprecated in Twisted 10.0.
z�spawnProcess called, but the SIGCHLD handler is not installed. This probably means you have not yet called reactor.run, or called reactor.run(installSignalHandler=0). You will probably never see this process finish, and it may become a zombie process.Nr5 r r r r r^ s �r^ �Twisted�

the value you might pass to L{os._exit}. This is L{None} if the
process exited due to a signal.

process did not exit due to a signal.
