Comment (by anders):

 Running trunk/2186 with polling instead of kqueue, I got this error also:

 {{{
 Child said (2, 58116): <<Assert error in bes_ClosedFd(),
 cache_backend_simple.c line 282:
   Condition((close(vc->fd)) == 0) not true.
   errno = 54 (Connection reset by peer)
 >>
 Cache child died pid=58116 status=0x86
 }}}
