SP2-0606: Cannot create SPOOL file
 

I am getting error as SP2-0606: Cannot create SPOOL file.
I did search on net and most of the post saying there is issue with permission of a directory.
#######################
Code:
path = XYZ/aaa
spool $path;
########################

But when I changed the LogFile creation path from XYZ/aaa to /tmp/aaa it's creating the aaa.lst file but
somehow it's not creating the aaa file.

So is the above scenario working corretly?

I am really confused with how spool works.

Which distro+version of Linux? What SW and cmd did you run/use to get that msg?

Red Hat Enterprise Linux Server release 5.4 (Tikanga)
