      Description

      The MariaDB server has crashed after trying to sync with the primary-active node during IST. I've uploaded 6 CSV files on the primary node with 2,3MBytes in size and after that inactive node Test5 has crashed after trying to synchronize during IST.
      After loading/insert of thrird CSV file Gcacge has been created "Created page /var/lib/mysql/gcache.page.000000 of size 134217728 bytes".
      CSV file is 2.3 MBytes and after the third, it is creating a new cache page with 128MB.
      Gcache settings: gcache.page_size = 128M; gcache.size = 4G;

      Test4 server was active, test5 was trying to sync data and it crashes after 51.4% with the message

      terminate called after throwing an instance of 'std::bad_alloc'
      what(): std::bad_alloc
      210616 10:54:31 [ERROR] mysqld got signal 6 ;
      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.

      To report this bug, see https://mariadb.com/kb/en/reporting-bugs

      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed,
      something is definitely wrong and this may fail.

      Server version: 10.5.10-MariaDB-log
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=0
      max_threads=153
      thread_count=21
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467871 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
