Thanks a lot for the app. That is what I was searching for!
There is a space with only one page, and two attached files of 2 and 5 megas
each. When I use dumping to directory only that space, I get the attached stack
(at the bottom you can see the Caused by: java.lang.OutOfMemoryError: Java heap
space:)
Then, I tried with 1800 Megas of RAM and IT WORKED, thanks be to the paging and
the swap memory.
I attach the error, for the eternity,
Thanks to everybody
