Re: [ferret_users] ferret memory allocation problem

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

Hi -
The message

Unable to allocate 100.0 Mwords of memory.

means that your computer system was not able to give the program that 
amount of memory.  This could be a limit on the memory installed on your 
system, or it could be that that amount of free memory was not available 
when you made the request.  Try it with 80, which is just larger than 
the amount Ferret says it needs; and if you still can't get that much, 
it may be possible to break up your calculation into smaller pieces.
