oai import error dspace 7.6.1

[Lucas Silveira]

    Dear Collegues, 

I am having a problem when trying to index the metadata using OAI import. In version 7.5, I was able to import all 42,000 items from the digital library. I installed version 7.6.1, and now when I try to run the command, I can only index 1/3 of the total, and it generates a Java heap error. Does anyone know if this is a common issue with version 7.6.1?

Thanks advanced.
