Trouble with checkpointing with Intel MPI using blcr

[hrscad_d_]

Trying to run checkpointing with BLCR using the Intel MPI 4.1.3.049 library. Compiled the source MPI codes using the Intel mpicc compiler. 

While running, used mpiexec.hydra -ckpoint on -ckpointlib blcr and other options. The checkpoints do get written, but the application crashes with a segfault after the first checkpoint itself (after having written a multi gigabyte checkpoint context file to disk). The applications run perfectly to completion when I run them without the checkpoint options. Also, checkpointing runs without problem when run on single node with multiple MPI processes.

The commandline options I use to launch the jobs are:
mpiexec.hydra -genv I_MPI_FABRICS shm:ofa -machinefile ./nodes -n 24 -ckpoint on -ckpointlib blcr -ckpoint-interval 300 ./MPIJob

What might be going wrong here?

Detailed outputs are given below:

# mpiexec.hydra -genv I_MPI_FABRICS shm:ofa -machinefile ./nodes -n 24 -ckpoint on -ckpointlib blcr -ckpoint-interval 300 ./lmp_linux -var x 120 -var y 180 -var z 240 -in in.lj

Running the same job without checkpointing results in the job running to completion: 

# mpiexec.hydra -genv I_MPI_FABRICS shm:ofa -machinefile ./nodes -n 24 ./lmp_linux -var x 120 -var y 180 -var z 240 -in in.lj
