    Description

      Mariabackup consistently hangs when you load data into a table from another table while a full backup is running.

      It hangs in the following phase:

      [00] 2019-05-15 01:23:27 Waiting for log copy thread to read lsn 5607063606354

      Before that, the following errors appear:

      [00] 2019-05-15 00:25:44 Retrying read of log at LSN=5593738149376

      [00] 2019-05-15 00:25:44 xtrabackup_copy_logfile() failed.

      This is regularly happening at a customer of ours.
      I was able to reproduce in my lab as follows:

      1. start a full backup
      2. run insert into empytable select * from sbtest1;

      Command line used for backup:

      mariabackup --backup --user=root --password=xxx --parallel=4 --extra-lsndir=/tmp --stream=xbstream --target-dir=/tmp/2019-05-16/mariabackup

      Isolation level: default (REPEATABLE-READ)
