Uwe Schindler commented on LUCENE-772:
--------------------------------------
I don't think we need to keep this issue open. It is no longer possible to
create compressed fields, Lucene 3.x can only read them. If they are corrupt
there is nothing we can do to fix it as this is a bug in JDK.
I would close this as won't fix.

> Key: LUCENE-772
> URL: https://issues.apache.org/jira/browse/LUCENE-772
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: 2.1
> Environment: Linux (gentoo 2.6.17 at least), jdk 1.5.0_06 and _08 at
> least, tomcat 5.5. IndexSearcher searching index mounted via NFS; using new
> lockless commits... We're using the 01-05-07 nightly build of lucene
> Reporter: Arthur Smith
> Fix For: 3.6.2
>
>
> Unfortunately I don't have a reproducible case of this (yet), but it's
> happened twice now on our production servers in the past few days, after we
> switched to the new lockless commits (thanks!). What we're seeing is the
> search thread running away in the middle of a seemingly ordinary search,
> after several hundred thousand queries that worked just fine. The search
> index is NFS mounted, and is updated every minute or so during the day by an
> indexing process running on a separate server. We do get occasional I/O
> errors, but we catch and retry and it seems ok after a few seconds.
> But twice now we've had run-away threads; the thread dump in both cases was
> caught in the middle of java.util.zip.Inflater:
