    Default Heap Lock Failure

    What is "Heap Lock Failure", and how can this be prevented?
    I have a set with cascading deletes/updates, and when marking a parent record, this message appeared several times. I did update the indexes for the child table, and that seemed to help, but not completely.

    Hi Richard,

    This has been a topic in the past. Do a search for Heap Lock Failure and you'll find your answer. I believe there will be an update sometime in mid January to address this issue.

    Richard, In an answer to this question a while back Selwyn wrote:

    it could be related to a corrupt index.

    is the table you are using on a network?

    try deleting indexes (the .cdx file for the table).

    do you still get the problem?

    try defining new indexes.

    I do not use a network. I did notice that some of the child records were marked and some were not when I marked the parent record. Perhaps building a new index would help. Thanks for the suggestion

    I had this problem for quite a while. I updated from build 95 to build 243 and although I still get them they do not occur with the same regularity. It seems to be a problem with index filters, the more you have the more the system breaks.
