OK that exception looks more reasonable, for a disk full event. But, I can't tell from your followon emails: did this lead to index corruption?
Also, I noticed you're using a rather old 1.6.0 JRE (1.6.0_03) -- you really should upgrade that to the latest 1.6.0 -- there's at least one known problem with Lucene and early 1.6.0 JREs.
