Re: [ferret_users] Memory limit

["Ansley C. Manke" <ansley.b.manke@xxxxxxxx>]

I'd like to add that the cause of any insufficient memory error is that 
the commands are trying to load more data into the memory that's been 
allocated, than there is space for. All versions of Ferret have logic 
that breaks up computations into pieces if possible, but for some 
expressions that is not possible.

If you send the commands you're using when the error occurs, showing the 
definition of the Ferret variables you have made, and the output of the 
command "SHOW DATA" for the relevant datasets, we may be able to help 
you work around the problem.
