I wasn't allowed to post the full strace, but here are the highlights... ---------- Forwarded message ---------- From: Johan Walles <[EMAIL PROTECTED]> Date: 2008/5/17 Subject: Strace output showing the problem To: [EMAIL PROTECTED]
Search for "= 3180". That will get you to the clone() call launching ps: clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x80ca878) = 3180 Note the result of the wait() call following it: waitpid(3180, 0xbf982e08, 0) = -1 ECHILD (No child processes) That's because SIGCHLD is being ignored. Later, we find the ps process we just launched, and warn about it. Note that 0xc6c == 3180: getpgid(0xc6c) = 2179 ... write(1, "Found HIDDEN PID: 3180\n", 23) = 23 Not ignoring SIGCHLD (see patch attached previously) fixes this.
