Resource leak or dead lock in the function task_dentry_path?

[Arkady <larytet at gmail dot com>]

Hi,

I have the following script

function task_cwd_full_path(pid)
{
        task = task_current()
        path = task_cwd_path(task)
        s = fullpath_struct_path(path)
        return s
}

global PATHS%;

probe kernel.function("do_execve")
{
        s = task_cwd_full_path(pid())
        PATHS[tid()] = s
}

probe syscall.fchdir.return
{
        s = task_cwd_full_path(pid())
        PATHS[tid()] = s
}

global Tick;

probe begin
{
        Tick = 0;
}

probe timer.sec(1)
{
        Tick = Tick + 1
        printf("Time=%4u\n", Tick)
}

I run the following loop in the shell

sudo find / -name '*' -type f -exec stat  {}  \;

I am getting "find: cannot fork: Resource temporarily unavailable" in
~60s on  ubuntu 4.4.0-59

What am I missing?

Thanks
