      I can't create Full backup of mariadb 10.6.
      Get this error:

      231101 10:55:34 [ERROR] mysqld got signal 11 ;
      

      Here is the command I run:

      /usr/bin/mariabackup   --verbose --backup  --extra-lsndir=$TARGETDIR  --user=mariabackup --password=xxx--stream=xbstream | gzip > $TARGETDIR/stream.xb.gz
