Good morning:

I am having this error "Error invoking unauthorized copy of runtime. Semaphore function error (Loc 809)." when I run a series of routines, the problem is that some days it runs fine without errors and others it begins to give this error. Anyone have any idea why? I don't really have stability in the process.

Thanks in advance.

What version of RM/COBOL and which operating system? 

This usually means the runtime system is being terminated without an opportunity to clean up.

Is article this any help? 

How do I address an "unauthorized use of runtime/compiler (Loc 810)" error message?

RM/COBOL Development System for Linux Intel 64-Bit installed in Ubuntu
