  • Closed as program error.

Error description

  • In rare cases, the server may crash as a result of a SELECT
    statement.
    There is no specific SELECT statement that causes this crash as
    it is dependent on the output returned and several other
    unlikely variables.
    
    Customer/L2 Diagnostics:
    The following message is reported in the dsmserv.err at the time
    of crash:
    ANR9999D pkmemory.c(798): Error 9 detected while freeing memory;
    free was called from tbnsql.c(412), memory was allocated from
    tbnsql.c(900).
