MySQL Cluster 6.1 - 7.1 Release Notes  /  Changes in MySQL Cluster NDB 6.1  /  Changes in MySQL Cluster NDB 6.1.3 (5.1.15-ndb-6.1.3) (2007-02-25)

Changes in MySQL Cluster NDB 6.1.3 (5.1.15-ndb-6.1.3) (2007-02-25)

This is a bugfix release, fixing recently discovered bugs in the previous MySQL Cluster NDB 6.1 release.

MySQL Cluster NDB 6.1 no longer in development.  MySQL Cluster NDB 6.1 (formerly known as MySQL Cluster Carrier Grade Edition 6.1.x) is no longer being developed or maintained; if you are using a MySQL Cluster NDB 6.1 release, you should upgrade to the latest version of MySQL Cluster, which is available from .

This Beta release incorporates all bugfixes and changes made in previous MySQL Cluster releases, as well as all bugfixes and feature changes which were added in mainline MySQL 5.1 through MySQL 5.1.15 (see Changes in MySQL 5.1.15 (2007-01-25)).


Please refer to our bug database at for more details about the individual bugs fixed in this version.

Functionality Added or Changed

Bugs Fixed

  • An invalid pointer was returned following a FSCLOSECONF signal when accessing the REDO logs during a node restart or system restart. (Bug #26515)

  • The InvalidUndoBufferSize error used the same error code (763) as the IncompatibleVersions error. InvalidUndoBufferSize now uses its own error code (779). (Bug #26490)

  • The failure of a data node when restarting it with --initial could lead to failures of subsequent data node restarts. (Bug #26481)

  • Takeover for local checkpointing due to multiple failures of master nodes was sometimes incorrectly handled. (Bug #26457)

  • The LockPagesInMainMemory parameter was not read until after distributed communication had already started between cluster nodes. When the value of this parameter was 1, this could sometimes result in data node failure due to missed heartbeats. (Bug #26454)

  • Under some circumstances, following the restart of a management node, all data nodes would connect to it normally, but some of them subsequently failed to log any events to the management node. (Bug #26293)

  • No appropriate error message was provided when there was insufficient REDO log file space for the cluster to start. (Bug #25801)

  • A memory allocation failure in SUMA (the cluster Subscription Manager) could cause the cluster to crash. (Bug #25239)

  • The message Error 0 in readAutoIncrementValue(): no Error was written to the error log whenever SHOW TABLE STATUS was performed on a Cluster table that did not have an AUTO_INCREMENT column.


    This improves on and supersedes an earlier fix that was made for this issue in MySQL 5.1.12.

    (Bug #21033)

  • Disk Data: A memory overflow could occur with tables having a large amount of data stored on disk, or with queries using a very high degree of parallelism on Disk Data tables. (Bug #26514)

  • Disk Data: Use of a tablespace whose INITIAL_SIZE was greater than 1 GB could cause the cluster to crash. (Bug #26487)
