As sent to the rsync mailing list on May 4, 2004:

(rsync 2.6.2 between two Linux systems) ...

What happens is that the sending rsync just appears to hang.  The
receiving rsync processes are no longer running when I go to look,
typically the next morning.
                                                                               
                                          
I finally managed to capture an strace of the receiving rsync
processes, which I've attached below.
                                                                               
                                          
The child receiver process gets an error return on a write(),
informs its parent by sending it two error messages, and calls
exit(11).  The parent receiver process reads the first of the
two error messages, but not the second.  It handles the SIGCHLD
signal after read()ing the first error message.  Thereafter, the
patent's select() no longer includes the file descriptor on which
(presumably) the second error message is waiting.  And it never
informs the sending rsync process of the error.
