Bugs Fixed

  • Connections using IPv6 were not handled correctly by mysqld. (Bug #42413)

    References: See also: Bug #42412, Bug #38247.

  • When a cluster backup failed with Error 1304 (Node node_id1: Backup request from node_id2 failed to start), no clear reason for the failure was provided.

    As part of this fix, MySQL Cluster now retries backups in the event of sequence errors. (Bug #42354)

    References: See also: Bug #22698.

  • Issuing SHOW ENGINE NDBCLUSTER STATUS on an SQL node before the management server had connected to the cluster caused mysqld to crash. (Bug #42264)

  • When using ndbmtd, setting MaxNoOfExecutionThreads to a value higher than the actual number of cores available and with insufficient SharedGlobalMemory caused the data nodes to crash.

    The fix for this issue changes the behavior of ndbmtd such that its internal job buffers no longer rely on SharedGlobalMemory. (Bug #42254)
