Plink out of memory error during ancestry match combine step

[h171e]

Got this error after increasing available ram to 7 Gb installed in the computer and updating the config to use up to 7 Gb of ram.

I wonder if there is an indication for required ram in the error message or if its due to required physical storage memory.

Last lines of the error message:

Error: Out of memory. The --memory flag may be helpful.
Failed allocation size: 1011902592

You'll need to allocate more memory to that process, maybe try 16 GB.
