Hi Kyle,

I have rebooted it couple of times. Did not have any impact, I doubt if that is the case because in the code before the mmap call there is check for the memory.

Please correct me if I am wrong.

Thanking You,

Now for 32GB I have increased it to 16384 entries and I am facing this error. I guess this is not because of the unavailability of physical memory.
