Gluster users - Aug 2018 - glusterd.log after server reboot: forced unwinding frame type / Error setting index on brick status rsp dict

Good morning,

today, after a gluster server reboot (including a brick not coming up,
which happens at every reboot), i've seen these error message in
glusterd.log file. Maybe i've copied+pasted too much, but i hope the
maintainers can sort it out :-)
