Server Error Report: 181171: SIGTERM

Good day all,
I run the DFT calculations (DMol3; Geometry Optimization task) of a short sequence of DNA using Discovery Studio 2016 and always find this error below.

Server Error Report: 181171: SIGTERM

I still find the same error while I resubmit the jobs many times and even by changing some parameters. 
For energy task, it remains fine and I got the result. Only the geometry optimization task will create this problem.

For your information that I am using RPBE, coarse (DN basis set) for simulating a short sequence of DNA. Anybody know the source of this error and its solution as well ? Is it related to the error in Centre for High-Performance Computing server? Thanks in advance.
