Are you sure that this is from the slave and not another not
requesting it? If this log entry has just ERROR, it means that the WAL
sender generated it. So don't you have a cascading slave connecting to
this new slave and requested for this WAL segment that has already
been removed?
Should the error come from the WAL receiver, you would have something like that.
FATAL: could not receive data from WAL stream: ERROR: requested WAL
segment 00000001000000000000001C has already been removed
