Signal #11 segmentation violation (SIGSEGV) trap or Access Violation in sqlm_write_applinfo. sqm_snapshot_buffer will probably be in the function stack above sqlm_write_applinfo. A memory writing function, such as _memmove or _milli_memcpy might be in the function stack above that. Here is an example stack top for a trap caused by this defect. ossDumpStackTrace OSSTrapFile sqlo_trce sqloEDUCodeTrapHandler ---- Signal delivered ---- _memmove sqm_snapshot_buffer sqlm_write_applinfo sqm_snap_appl sqlmonssagnt sqlmonssbackend
