If
* BLR replicates from a node in a Galera cluster and
* writes are made to all nodes in that cluster,
then
* if a slave to BLR is stopped when it has received an event
originating in a node different than the one BLR is replicating
from
the subsequent (re)starting of the slave will fail because BLR looks
for the last event from a file whose path contains the server id of
the node where the event originates, although it should look for it
in the file whose path contains the server id of the node from which
BLR replicates.
