Duh some unix syscall semantic peculiarities ? :-)

my box is a mac air 11", core2 duo 1.4GHz. I run ocaml with jeremy dimino gprint patch I must confess.

mjambon commented 12 years ago

I tested on the Mac of a colleague and the programs succeeds, despite printing all these "[err] kill worker" errors that I don't see on Linux. This is its configuration:

$ uname -a Darwin hume 11.2.0 Darwin Kernel Version 11.2.0: Tue Aug 9 20:54:00 PDT 2011; root:xnu-1699.24.8~1/RELEASE_X86_64 x86_64

It would help if you could confirm the bug with a standard installation of OCaml 3.12.1 and Lwt 2.3.1 (the one in Godi) or lwt 2.3.2 (latest).

Thanks for your contribution.

mjambon commented 12 years ago

Error 2 is EAGAIN ("Resource temporarily unavailable") obtained as follows:

# (Obj.magic 2 : Unix.error);;          
- : Unix.error = Unix.EAGAIN
# Unix.error_message (Obj.magic 2);;
- : string = "Resource temporarily unavailable"

The Linux man page for fork() says:

ERRORS
       EAGAIN fork()  cannot  allocate  sufficient memory to copy the parent's
              page tables and allocate a task structure for the child.

       EAGAIN It was not possible to create a new process because the caller's
              RLIMIT_NPROC  resource  limit  was  encountered.  To exceed this
              limit, the process must have either  the  CAP_SYS_ADMIN  or  the
              CAP_SYS_RESOURCE capability.

       ENOMEM fork()  failed  to  allocate  the  necessary  kernel  structures
              because memory is tight.

Do you think you might have a memory quota or a maximum number of processes?

I will try to catch these errors and print better messages but it won't solve your problem.

mjambon commented 12 years ago

You can check for your system limits with "ulimit -a" and the current number of processes with "ps ax | wc -l".

Bonjour Martin,

ma version d'OSX : Darwin air.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386

c'est un mac air 11", le ulimit est rel. bas concernant les processus, mais j'en ai que 76 actifs :

philou@air:~/src/ml/nproc-git$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 256 pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 266 virtual memory (kbytes, -v) unlimited

tant mieux si toutes ces exceptions sont "harmless", je vais tester nproc un de ces jours à ce moment là. le fork: je n'avais pas fait attention au EAGAIN. le kill puis waitpid, j'ai essayé de remplacer sigkill par sigterm, mais j'ai autant de EINTR.

je verais pour réinstaller un ocaml "genuine" sans le patch gprint, j'avoue avoir la flemme, quoique si il n'y a que lwt comme dépendance...

salutations.

Il est fort possible que ce soit ca. A plusieurs reprises, les tests de test_nproc.ml creent 100 processus "workers". Il suffit qu'ils ne soient pas correctement termines pour que la limite de 266 soit atteinte.

Je viens faire une modification qui consiste a reessayer d'appeler waitpid s'il est "interrompu" par EINTR. Essaie la nouvelle version de developpement.

philou@air:~/src/ml/nproc-git$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 256 pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 266 virtual memory (kbytes, -v) unlimited

tant mieux si toutes ces exceptions sont "harmless", je vais tester nproc un de ces jours à ce moment là. le fork: je n'avais pas fait attention au EAGAIN. le kill puis waitpid, j'ai essayé de remplacer sigkill par sigterm, mais j'ai autant de EINTR.

je verais pour réinstaller un ocaml "genuine" sans le patch gprint, j'avoue avoir la flemme, quoique si il n'y a que lwt comme dépendance...

Bon de toute facon, ca m'etonnerait que le patch y soit pour quelque chose.

Martin

salutations.

I tested on the Mac of a colleague and the programs succeeds, despite printing all these "[err] kill worker" errors that I don't see on Linux. This is its configuration:

$ uname -a Darwin hume 11.2.0 Darwin Kernel Version 11.2.0: Tue Aug 9 20:54:00 PDT 2011; root:xnu-1699.24.8~1/RELEASE_X86_64 x86_64

It would help if you could confirm the bug with a standard installation of OCaml 3.12.1 and Lwt 2.3.1 (the one in Godi) or lwt 2.3.2 (latest).

Thanks for your contribution.

I added a retry loop for the waitpid function, which should take care of reclaiming the child processes. Let me know if it works.

avec la nouvelle version git cela semble bon ( noter que rhausser la limite du nombre de process n'a rien chang):

j'attache deux traces dtrace du nombre de syscall passs par les processes test_nproc entre avant le spin loop sur waitpid et maintenant (il est identique, mais je dcouvre dtrace :-) dtrace -n 'syscall:::entry { @num[pid,execname] = count(); }'
