> and this is happening quite frequently, although I am not able to reproduce it on demand, I saw an issue logged which is some what related to mine issue (http://mail-archives.apache.org/mod_mbox/lucene-solr-user/200809.mbox/%3C6E4A40DB-5EFC-42DA-A857-D59F4EC3496B@mikemccandless.com%3E) but the only difference here is I am not using Store.Compress for my fields, i am using Store.NO instead. please note that I am using IBM JRE for my application.
> Is this an issue with lucene?, if yes it is fixed in which version?
