Subject Re: java.lang.OutOfMemoryError: Java heap space when sorting the fields
Date Tue, 18 Mar 2008 15:19:47 GMT
This is because sorting will load all values in that sortFirled into memory.

If it's an integer, you will need 4*N bytes, which is additional 52M for you.

There is no programatical way to increase memory size.
