Someone in the lab that I work in has been trying to run some calculations with NWChem and I've been trying to help him get started running it with MPI. It has been a bumpy ride, however. At first, we were getting problems about not being able to allocate a shared block of memory. SHMMAX was already plenty high (as large as all of the physical memory), so I created a swap file, started calculations again, and waited.
Now they are crashing again, but this time with a much different error message. From what I can tell, it is another problem with allocating shared memory, but it seems like NWChem is passing an invalid (i.e., negative) number to the allocation function.
Here is the relevant error message:
0:CreateSharedRegion:kr_malloc failed KB=: -772361
(rank:0 hostname:vivaldi.chem.utk.edu pid:3128):ARMCI DASSERT fail. ../../ga-5-1/armci/src/memory/shmem.c:Create_Shared_Region():1188 cond:0

And just in case, here is a link to the full output file:
