Error description
When a user is querying sysmaster:systcblst, it is possible that the thread may generate an assertion failure which brings the server down if the tcb it's looking at is freed and reused. The stack for the crash looks as follows: afstack mt_ex_throw_sig afsig_handler <signal frame> mt_prtcblst pstread pst_rsread rsread fmread readseq_single gettupl scan_next next_row hash_process_all_groups group_open prepselect open_cursor sql_open sq_open sqmain spawn_thread startup It's also possible the stack may include nxttcb() which would be between mt_prtcblst and the signal frame, as that is the function where the code is actually having problems, but this function can be in-lined on some platforms which makes it non-visible on the stack.
