[daip] IMAGR memory problem

[Hanno Spreeuw]

Hi Eric,

I reinstalled the LNX64 binaries and it works fine.
I am imaging 235 facets from a 285 MB dataset.
When I set the MAXAP to 512 MB or 1024 MB it works fine.
Of course, I should set it slightly lower than 512 MB, but I was trying 
a few different values.
If I set MAXAP to 4GB I get another memory allocation error, although I 
have almost 6GB RAM available.
This I don't understand.

Hanno.
