Michael McCandless commented on LUCENE-772:
-------------------------------------------

Olivier, in your case are you certain you did not add compressed fields, yet 
Lucene is trying to decompress the fields on loading?

In which case this sounds like index corruption that unfortunately causes zip 
to be invoked on invalid data, which it turn can apparently cause zip to enter 
an infinite loop.

Unfortunately, once an index is corrupt it can cause any number of crazy things 
to happen.  We need to get to the root cause of the corruption.  So it's not 
clear on upgrading to 2.4.1 with a still-corrupt index, whether 2.4.1 will 
behave any differently.  It's still worth a shot: upgrade to 2.4.1 and run 
CheckIndex with java's assertions enabled, and see what happens?

>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: Search
>    Affects Versions: 2.1
>         Environment: Linux (gentoo 2.6.17 at least), jdk 1.5.0_06 and _08 at

> 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
