      Linux version 2.6.32-5-amd64 (Debian 2.6.32-35) (dannf@debian.org) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Tue Jun 14 09:42:28 UTC 2011

    Description

      We have been running with default spider parameter for a while without issue

      After changing some spider parameters on all the slaves
      spider_crd_sync = 0
      spider_same_server_link = 1

      Only the slave used for backup was crashed

      Note that the spider partitions is pointing to mixed remote and local innodb tables

      Intresting is that the mysqldump that break is having --no-data

       -u${user} -p${passwd} -h${host} --database ${_db} \
              --allow-keywords --comments --add-drop-table=FALSE \
              --flush-logs ${master_opt} ${tables_opt} --routines --triggers --no-data \
              > ${working_dir}/${_db}-struct-dump.sql 2>${working_dir}/${_db}-struct-dump-error.log
