IndexModifier hanging

[gawron]

Hi,

I am running wikiprep-esa tying to reproduce the results in the GM paper, and I have gotten as far as the last step, running the IndexModifier (dont have 16 GB of RAM).
It has been running for 40 + hours and the file vector.txt is still a 0 sized file, but as far as I can see that file should be large before sorting and be replaced by vsorted.txt after, so it looks like it hasnt even started sorting yet. I have a text table with 127,495 elements and ESAWikipediaIndexer.java seemed to run in good order, creating a 557 Meg index directory. But after 40 hours I have this 3Meg java process that seems to be doing nothing. Can you verify that something is wrong, or am I misunderstanding normal behavior? The command I ran was:

java -cp $CLASSPATH:esa-lucene.jar edu.wiki.modify.IndexModifier concept_index

There has been no output from the program. (Note this is the last version wikiprep-esa).Any suggestions would be appreciated.
