Thanks for the reply. When the run on Cray system was allocated a total memory of 2000mb , the last few lines of NWChem.6.5.e29089 error file are following:
...................................................................................................................................................................................
libhugetlbfs [nid00051:8126]: WARNING: New heap segment map at 0x10067800000 failed: Cannot allocate memory

[NID 00051] 2014-11-12 14:39:25 Apid 109986: OOM killer terminated this process.
However, when the run on Cray system was allocated a total memory of 5000 mb, the run terminates immediately with the nwc.out file with the message:

and the last few lines of the error file are:
