I'm using Chicken 4.10.0 and with the below script chicken rapidly
allocates memory then seems to get stuck:
=====script=====
(define start-time (current-milliseconds))
(define max-n 200)
(let loop ((n 0)
(stuff '()))
(let ((bigvec (make-vector 1000000 0)))
(print n " Elapsed time: " (/ (- (current-milliseconds) start-time)
1000) " s ")
(if (< n max-n)
(loop (+ n 1)(cons bigvec stuff)))))
=====end script=====
On a machine with lots of memory, nothing in cache or buffers:
> free -g; utils/memproblem-simple
total used free shared buffers cached
Mem: 1009 13 996 0 1 1
-/+ buffers/cache: 10 999
Swap: 512 0 511
The program chokes after 133 rounds through the loop. No "out of memory'
message. The process memory usage doesn't seem to grow and the program just
hangs. I added -B: but didn't get any output.
Suggestions on what might cause this and if so how to work around it or how
to debug further?
0 Elapsed time: 0.007 s
1 Elapsed time: 0.027 s
2 Elapsed time: 0.031 s
...
131 Elapsed time: 2.09 s
132 Elapsed time: 2.093 s
133 Elapsed time: 2.768 s
^C
(I gave up waiting)
