It seems that SYSTEM executes FORK which is unable to create a new : process. : Any ideas? What version of the operating system are you working on? This problem sounds familiar. If I recall, the problem has something to do with memory allocations in the SR5 space that prevent the process data space from being copied to the child during a fork() call. I think this problem was fixed, does it still occur on the 5.0 push? If it still happens on 5.0 push, you may have a new problem. Steve
