12 years ago The error 23 that occurs during fork() is ENOMEM "Not enough space" (given by (Obj.magic 23 : Unix.error);;).
Let me know if you still see the problem or if it is explained by a quota issue (ulimit -a).

12 years ago Hello Martin,
It's running fine since the last git commit some 10 days ago (here on the mac air with untuned and fairly low ulimit):

12 years ago I was just wondering about the problem you witnessed on Debian, not the one on the Mac (issue #1) which appears to be resolved.

12 years ago ah oui je l'avais ignorée celle-ci, passant plus de temps sous osx. elle est tjr présente, mais cette machine et une "fille" openvz avec 768MB de RAM allouée, de plus, j'ai l'install ocaml dans un chroot deboostrap dans cette fille. cela fait passablement de poupée russe.

j'ai essayé d'augmenter le max stack size à 128M, la taille de mém. lockée à 4096 k, cela ne change rien. pipe size j'imagine que c'est la "profondeur" en mém par block de 512 bytes, je ne peux pas la modifier.
c'est une debian unstable dans ce chroot.
Salutations.
