After it worked on Fr, Sa and Monday, this morning they dissapeared at
our main site for the first time. This vm has 6GB memory and 4 cpu cores
assigned and it is the first time the [homes] share stopped working.
Even after restarting samba wbinfo -u und wbinfo -g takes sometimes up
to 30 seconds to enumerate users/groups.
