[mpich-discuss] MPICH Trouble:failed to connect. Seek help

[Jayesh Krishna]

Hi,
 Did you install MPICH (MPICH 1) or MPICH2 on your systems ? MPICH (MPICH 1) is very old and we recommend all users to move to MPICH2.
 Try installing the latest stable release, 1.3.1, of MPICH2 (available at http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads) and let us know if you still have any issues.

Regards,
Jayesh

Dear Sir： 
First of all, thank you for your excellent MPICH! It helps us a lot. 
But I have some trouble puzzles me. 
I compiled a parallel code system with MPICH NT 1.2.3 x32 on Windows XP x32.And installed MPICH NT 1.2.3 x 32 on Windows Server 2003,64 bit system ,a computational cluster with 12 nodes.And I ran the code system on the cluster with MPICH NT 1.2.3.Sometimes it's OK,but sometimes it failed and show the information: failed to connect nodeX and there is no process of this code on nodeX.After I restart the server of MPICH it can work well. 
And my question is why it failed sometimes and how can I make it stable and don't need to restart the server of MPICH? 
Thank you very much!
