I'm running Lua 5.1.3 on OS X 10.11.3. The application in question is mostly database work using luasql.postgres

Every now and then I get something like:

lua(45734,0x7fff7ab92000) malloc: *** error for object 0x10001f6c0: pointer being freed was not allocated

*** set a breakpoint in malloc_error_break to debug

Abort trap: 6

I suspect that this is only occurring when there is a large amount of data to process.

Any suggestions as to how to handle this sort of situation (presently the process is being restarted repeatedly until all the data is processed and then the issue goes away).

We could live with it but it bugs me.
