Jan Eerdekens commented on LUCENE-6725:
---------------------------------------
Currently reproducing this behaviour is difficult as we're seeing the following:
- the problem seemed to occur consistently on our production environment (but
we can't tried it a lot there for obvious reasons)
- after installing a monitoring tool today (a Java agent) the next reindex
didn't crash the JVM
- the problem (at first) didn't happen on our pre-production environment (which
is the most similar with regards to CPU/memory/... to production)
- in the weeks after discovering the problem, it also happened once on the
pre-production environment, but on retrying the reindex afterwards it didn't
happen again
- the problem isn't reproducible on our test environment or local machines
(Apple MacBook Pro's)
We also created a small standalone Java tool that is also able to do the
IndexWriter.deleteAll() call on a copy of the index, but that doesn't trigger
the same JVM crash on our production and pre-production environments (using in
the same JVM version).

> 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
> #
> # JRE version: Java(TM) SE Runtime Environment (7.0_75-b13) (build
> 1.7.0_75-b13)
> # Java VM: Java HotSpot(TM) 64-Bit Server VM (24.75-b04 mixed mode
> solaris-sparc compressed oops)
> # Problematic frame:
> # J 5227 C2
> org.apache.lucene.index.IndexFileNames.segmentFileName(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
