rsync on F11 on XO-1 is giving me trouble

I have a "permanent" SD card in each of my XOs, and use 'rsync' to 
keep the contents of these SD cards synchronized between systems. 
Lately I've been encountering a lot of trouble with using 'rsync' 
between F11-on-XO systems.  Typically, the data transfer stalls (and 
sometimes leaves the receiving-end SD card corrupted).

I'm not sure which end of the rsync data transfer is at fault.  The 
daemon (sending) end is left high and dry, but at least in that 
machine I can continue (and 'kill -2' the daemon, if need be).  The 
machine at the receiving end typically becomes unresponsive (often 
the only thing I can do is to power off).  My guess is that the 
receiving end may be running out of memory (though I *do* have a 
swap partition defined).

I'm not writing a bug report, because I cannot deliberately 
reproduce this (it just happens, sooner or later).  I'm seeing this 
both with recent rawhide-xo builds and with recent SoaS builds.
