Memory problem

Dear Forum,

I am using openmx for interface optimization. The job are always stopped for memory shortage.

Linux kernel claimed as following:
Aug 21 17:59:11 node05 kernel: Out of Memory: Killed process 26518 (openmxp).

But there are 8Gb memory available for use! and I checked the mywork.memory1 file (the job used 3.6 Gb memory in divide-conquer:residues)

When I run in parallel version of openmx. the log file indicate as following:

******************* MD= 1 SCF= 1 *******************
<DC> Eigenvalue problem...
-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.

PID 26518 failed on node n0 (192.168.128.5) due to signal 9.
-----------------------------------------------------------------------------
Can anyone gives me hints on this problem? Or changing some options in input file can reduce memory use?

Thank you in advance.
