[mpich-discuss] importance of /tmp/mpd2.console_root?

[Sangamesh B]

Hi all,

     I want to know the importance of "mpd2.console_root" file.

     This file gets created after launching the mpd's in /tmp directory.

srwxrwxrwx 1 root   root      0 Oct  3 11:21 mpd2.console_root

     When mpd's are stopped, this file get deleted automatically.

I'm curious to know about this because, recently I faced a problem with
mpdboot. mpdboot was not happening and gave error with a particular node. I
googled the error, then I came to know that its problem with the above file.

Eventhough, there was no mpd(as user root) running on that node, the file
/tmp/mpd2.console_root was present. I tried to delete. But it couldn't
delete.

So why this file is required? In the above case what's the wayout?

Thanks,
Sangamesh
