This is unfortunately a fairly generic error message that means the
remote/child process died suddenly without passing back any information
about why.

Here's a message from Wayne on why the error message is so generic:

I'd suggest following the same debugging steps I used to track down a 2GB
bug on HP-UX:

The best results were from running rsync under "tusc" (in your Linux case
it would be "strace") and sifting through the voluminous output to find
the write() that failed and why.
