Same here, I have just one machine running jessie, FWIW it seems that 
what triggers the problem is an rsync connection from another host.
Unfortunately nothing gets logged (the last message in syslog is the 
rsync connection) and nothing on the console.
The (virtual) machine is totally unresponsive and the hypervisor warns 
about high guest cpu usage (100%).
