That’s not an indication that the application is correct with more processes.  Many applications work at smaller scales but fail at larger scals.  From the error, the indications point to the application.  I’d recommend digging into the application and figuring out what’s breaking.  The -print-all-exitcodes that Sangmin suggested, or attaching a debugger might be useful for this.
