GNU Parallel Bug Reports --memfree option not working

[Jon Puritz]

Hi,

I am using GNU parallel 20150622 on Scientific Linux 7.1 (Nitrogen) and am having trouble with the —memfree command.  Basically, no matter what value I put for the command, parallel will not start any processes.  Even the command:

echo "1" | parallel --memfree 1 echo {}

will never start.  The system I use has over 128 GB of RAM and there is several GB free.  

Any thoughts?

Thanks,

Jon
