When the program is run individually on each nodes, it works fine. I
have tried it on all the individual nodes. The problem comes up only
when I run it across the nodes.

AFAIK, the only difference across the nodes is that their times are
not synchronized.

node2Tue Jun 12 08:49:17 EDT 2007
node3Tue Jun 12 14:19:49 EDT 2007
node4Tue Jun 12 13:48:01 EDT 2007

I asked the administrator to synchronize the timings. I will inform
here if synchronizing the timings has any affect on the code's
