In sys.c:set_user() we see
if (atomic_read(&new_user->processes) >= current->rlim[RLIMIT_NPROC].rlim_cur && new_user != &root_user) { free_uid(new_user); return -EAGAIN; }
which was added in patch-2.6.0-test2. No doubt this causes your problem.
You might check what values these variables have for you.
