Details

    Description

      The mariadb server hung when dumping data using mysqldump:

      root      248699  248698  0 Sep23 ?        00:00:00 /opt/LU3P/bin/mysqldump --defaults-file=/etc/opt/LU3Pmysql/webnms/my.cnf --force --single-transaction WebNmsDB MediaPlaneElement UserPreferences pm_dashboard_data_table ngfm_AlarmSeverity pmchartconfigs ngfm_OssFilter pm_media_attributs_list_table ngfm_ProbableCauseText pm_media_collection_table ngfm_Comment OAMManagedElement pm_parse_history ngfm_AlarmFilter ngfm_HistoricalComment ngfm_AdvancedFilter pm_media_job_table -uEUbtiVBaRowtEYT1 -px xxxxxxxxxxxxxx
       
      mysql       3725    2893  0 Sep23 ?        00:09:28 /opt/LU3P/sbin/mariadbd --defaults-file=/etc/opt/LU3Pmysql/webnms/my.cnf --basedir=/opt/LU3P --datadir=/var/lib/db/webnms --plugin-dir=/opt/LU3P/lib/mysql/plugin --user=mysql --log-error=/var/opt/log/mysql/webnms/mysql.err --pid-file=/var/opt/run/mysql/webnms/mysql.pid --socket=/var/opt/run/mysql/webnms/mysql.sock --port=3306
      

      Any connection made to the MariaDB server just stuck there without return. Logging seems also blocked as no error log printed since the hang. And it still hangs as of now (for >24h).

      Attached the config file my.cnf and the thread dump gcore_threads_dump.txt from the core file that is generated by gcore cmd against the hung MariaDB instance.

      Let me know if more info is needed.
