"Chunk not locked" is displayed in MemLocalIDToPtr. This function is called a
lot in DmInsertionSort, so nailing down the specific problem is tricky.
However, I'm concerned at your number of records. It's over 35,000. I notice
that DmInsertionSort uses ints (16-bit values), so there could be some overflow
problem there.
DmNumRecords returns a UInt, implying that only 64K records are supported. From
the problem you've turned up, perhaps internally only 32K records are supported.

I am not sure what I did wrong... This is what I did;
typedef struct{
Char prodID[MaxProdIDLen + 1];
Char prodAlt[MaxAltIDLen + 1];
Char prodDesc[MaxProdDescLen + 1];
} FeiProduct;
static Int CompareIDFunc(FeiProduct *rec1, FeiProduct *rec2, Int unusedInt,
SortRecordInfoPtr unused1, SortRecordInfoPtr unused2,
VoidHand appInfoH)
{
Int result;
result = StrCompare(rec1->prodID, rec2->prodID);
return(result);
}
In Main program;
ldbP = DmOpenDatabaseByTypeCreator(opening with dmModeReadWrite);
if (lpdP)
{
DmInsertionSort(ldbP, (DmComparF *) CompareIDFunc, 0);
DmCloseDatabase(ldbP);
}

I've seen that alot. When you go to write to your record, are you
locking the pointer? Like this:
recP = MemHandleLock( Record );
// do processing
MemPtrUnlock( recP );
Sometimes I get that message if I unlock a pointer twice (or unlock
an unlocked pointer).
