FAQ: How to deal with out of memory errors on Windows
I'm running out of memory in Windows using harpoon, what can I do?
When you allocate in Windows and then allocate more memory, Windows is
prone to memory fragmentation, dividing the "available" memory into
As of version 1.4.9(d) there is a winmem option as follows.
The winmem option checks the available system memory up front then
tries to allocate a single large chunk of memory to avoid fragmentation.
The winmem option is to be used after you run harpoon and find that it
runs out of memory as a second attempt at allocating memory.
If harpoon -winmem fails up front then it is trying to allocate
"available" system memory which is probably overly optimistic given the
existing fragmentation. So it is failing. If you are using other apps on
Windows, then you may have already fragmented the memory space. Try
harpoon -winmem after a fresh reboot with no other applications running.
