Comment (by Robert Verspuy <robert@…>):

 Same here, although the process on my BE is only taking 4% CPU load (IPTV
 recording). The deadlock also appears, when no FE is ever connected to the
 BE, but it does looks like it is somehow related to recordings that keep
 running. The logfile of the BE tells me the recording is stopped, but the
 mpg file on the disk keeps growing.

 I connected to the BE process with gdb. See backtrace below:
