Local fix

Problem summary

  • Problem exposes when a Linux box is configured with
    non-contiguous nodes. When JVM is enabled with numa support,
    call to numa_all_nodes always returns the nodes starting from
    node0 till the highest node_ID. This way the nodes that are not
    really available are also being considered and is causing the
    mbind error.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR8
    5.0.0 SR12
    Problem is addressed in such a way that the nodes returned from
    numa_all_nodes are validated for their availability and
    constructs the correct set from numa_all_nodes.
    .
    To obtain the fix:
    Install build 20100213 or later
