I understand that adding the shebang makes it likely that this was
something to do with the script, but was wondering if somehow the
"free" error was actually coming from boincmgr.
Also, any chance in the past you invoked it as "sh script.sh" as
opposed to "./script.sh"? And now you are just doing "./script.sh"?
That would explain the change in behavior.
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?
