  • Closed as program error.

Error description

  • "CSV0021 requests for module DLM$READ exceed maximum use count",
    which indicates that the module's CDE use count exceeded the
    system limit of 32,767.
    This typically occurs when a module is repeatedly loaded or
    referenced via LINK, XCTL, ATTACH,or LOAD macrosâ--implying
    that the DLM load module is being called excessively, likely
    due to the query execution pattern.
