Thanks - Brad also responded off-list. Problem was that our /tmp file
constraint was quite a bit smaller.

Ralph, is it not the mpool_sm_max_size? 512MB seems to be the
default max size per node.

Yo folks
As has frequently been commented upon at one time or another, the
shared memory backing file can be quite huge. There used to be a
param for controlling this size, but I can't find it in 1.3 - or
at least, the name or method for controlling file size has morphed
into something I don't recognize.
Can someone more familiar with that subsystem point me to one or
more params that will allow us to control the size of that file?
It is swamping our systems and causing OMPI to segfault.
Thanks
Ralph
