Thanks Henri, I do not know strace. I've attach it to the stuck process, it fill me a log file with :
7562 recv(6, "", 5, 0) = 0
7562 select(7, [6], NULL, NULL, {2, 0}) = 1 (in [6], left {1, 999998})
7562 ioctl(6, FIONREAD, [1]) = 0
7562 time(NULL) = 1406617706
7562 time(NULL) = 1406617706
7562 select(7, [6], [6], NULL, {1, 0}) = 2 (in [6], out [6], left {0,
999998})
7562 select(7, [6], NULL, NULL, {2, 0}) = 1 (in [6], left {1, 999999})
7562 ioctl(6, FIONREAD, [1]) = 0
7562 time(NULL) = 1406617706
7562 time(NULL) = 1406617706
The five last lines are repeated indefinitely.
It help someone to understand ? because me... no!
