ctdbd error out 'ctdb_send_dmaster_reply unable to update dmaster'

[Yu Liao]

Hi,

I configure the samba server under ctdb mode, it works fine for couple of
days.  Yesterday, the ctdbd is crashed and error out 'ctdb fatal error:
ctdb_send_dmaster_reply unable to update dmaster'. What is the possible
reason of the error?
