Subject [jira] [Commented] (LUCENE-6725) Reindex crashes the JVM
Date Mon, 10 Aug 2015 07:40:46 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-6725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14679724#comment-14679724

Dawid Weiss commented on LUCENE-6725:
-------------------------------------

Hi Jan. Well, if you can run Lucene tests from the 5.x branch (and trunk) it'd be nice to
know they pass (or fail). Should the tests fail, try to re-run them with the same "randomization
seed" -- the full repro line is typically printed when a failure happens (not in Lucene 3.5
though).

If something is reproducible, we'd definitely want to know about it (and so would probably
the JVM folks). hotspot logs and test output logs would be very handy (so tee them to a file,
if you can). 

If you have time, a full run is great:
{code}
ant test
{code}

If you don't, then just the core tests should also do:
{code}
cd core
ant test
{code}

> We're using Liferay which uses Lucene behind the screens to index things like documents,
web content, users, etc... . When we trigger a full reindex via the Liferay Control Panel,
which uses IndexWriter.deleteAll(), the JVM crashes and generates a dump with the following
message: 
> #
> # A fatal error has been detected by the Java Runtime Environment:
> #
> #  SIGSEGV (0xb) at pc=0xffffffff78de94a8, pid=18938, tid=2478
