Problem Description: When running real.exe in WRF, it frequently crashes during the 1979-2000 runtime period. The server should have sufficient memory. The rsl.error.0000 log shows garbled characters after the last timestamp before the crash. Attempts using different grid configurations resulted in different crash timings. How can this issue be resolved?
The real.exe run is interrupted

Hi,
That is a strange issue that i've never seen before, and it's likely specifically related to your computing environment. I would like to check your rsl* files, though. Can you package all of them into a single *.tar file and attach that, along with your namelist.input file? Thanks!

Hello, thank you for your response. I have packed and uploaded the attachment. When I adjusted the grid size to 130x130, the program ran successfully. However, with other grid configurations, the process would abort and encounter issues mentioned in the rsl.error.0000 file.
Thanks for sharing that, and apologies for the delay in response. I am still unsure why you are getting the odd symbols in the rsl file - you may need to discuss that issue with a systems administrator.
Regarding the model failing, though, and working with a smaller domain - I see that you are only running this with a single processor, based on this line in the rsl file:
You will almost certainly need more than 1 processor to run this. I'm not sure how many you have access to, but with a domain size of 160x160, you will need to use somewhere between 1 and 256 processors. See Choosing an Appropriate Number of Processors for more information.
