Java heap space

Submitted by Eelco Visser on 23 May 2011 at 12:39

try increasing the max heap space in eclipse.ini (e.g. -Xmx2G)

I’ve changed the file format of dependency file from textual to streaming aterm, trimming the file from 2 MB to about 400 KB in the researchr case.
Not sure if this fixes the memory issue however.
