The subject pretty much says it all. The java dump says it crashed
somewhere in the memory mapped file code. I change an index from
"memory" to "mmapfs" a couple of days ago. We are running Centos 6.
I can supply a dump file if needed.

The dump would help, can you also provide the Java version and elasticsearch version used?

Shay,
We are running Elasticsearch 0.18.6 and Open JDK 1.6. Dump file can
be found at [http://dl.dropbox.com/u/59098143/hs\_err\_pid14684.log](http://dl.dropbox.com/u/59098143/hs_err_pid14684.log)
Thanks,
Jason

Thanks!, I believe this will be fixed in the next Lucene 3.6, [[LUCENE-3588] Try harder to prevent SIGSEGV on cloned MMapIndexInputs - ASF JIRA](https://issues.apache.org/jira/browse/LUCENE-3588), though it is interesting when it would happen.
