Doesn't the MS kill the job if one or more IM polls fails?  We see these in our MS logs fairly often:

pbs_mom;node_bailout, 242745.tbird-admin2 POLL failed from node dn637 7)
242745.tbird-admin2;kill_task: killing pid __ task __ with sig 9
pbs_mom;node_bailout, node_bailout: received KILL/ABORT request for job 242745.tbird-admin2 from node dn637

And the user's .e file contains a 1099 error like this:
=>> PBS: job killed: node 7 (dn637) requested job terminate, 'EOF' (code 1099) - internal or network failure attempting to communicate with sister MOM's

I assumed you'd have to comment out the "send_sisters(pjob,IM_POLL_JOB)" portion of the main mom loop to avoid that.  Maybe I'm missing something though.
