The run_manager script was originally create going back to 2005, and didn't have the #! line and had worked fine till this time. Strange thing is I tried to repeat error later, and it ran fine without the #! line?? Had seen the same error earlier when I had a 1 line script, and it gave same error. Found error in search, and seems to link it to a cpp program and memory issue. Machine has 16M ram and has 3.5M Free with 8M in buf/cache so about 4.5M being currently used by system. So, not sure why it came up, and now isn't coming up? +------------------------------------------------------------+ Michael D.
