When you experience the error below. According to the FAQ,

My job crashed with PBS: job killed: node 1 ($NODENAME) requested job terminate
, 'EOF' (code 1099) - received SISTER_EOF attempting to communicate with 
sister MOM's

This could be caused by a failed node.

But recently I'm seeing this error from a code run and the issue as that the code took took too much memory and the result was a node hang. The above result ensues.
