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?
