 Using bindctl:

 {{{

 > Stats show
 send the command to cmd-ctrld
 Error!
 Fail to connect with b10-cmdctl module, is it running?

 }}}

 It is running.

 This kills bindctl at next input there.

 I also get the following from the server (not bindctl) when the error
 happens:

 {{{

 }}}

 But cmdctl is still running. It never stopped (same process start time).

 And cmdctl still works fine for other things. I can use bindctl fine other
 than the "Stats show" (but I didn't try every combination).
