insufficient memory: "allocate (psi(...))' returns an error code.

nobody is sure how it works. Consider that you have all kind of stuff
running on the same memory, all kind of stuff that comes with the
program (the executable itself, libraries, etc), that the memory report
may not always (and maybe ever) be accurate (it isn't for sure if you
do any nonstandard calculations), that a process may have further
limitations to the memory it can access (typically smaller than the
physical memory), etc.
