Please any body help me to get rid of this error. During WRF-ARW simulation this error abort the simulation in middle.

Please provide your suggestion to resolve the issue.

Your job has a memory problem. Not all ALLOC failures may have been caught in the code.
This leads to strange things happening such as "memory corruption", sometimes with some
very bizarre tracebacks.

If you are running MPI, try adding more nodes. Depending on the memory per node, you may have to reduce the number of cores per node you are using. Only experimentation will help, as all supercomputers are different.

If non-MPI, then you have a bigger problem. Make sure no other programs are running when you are. You might have to reduce the problem size in this case.
