Looks like the problem is somewhere in MMapFSDirectory. As soon as I
switched to NIOFSDirectory, JVM stopped crashing. Maybe MMapFSDirectory
shouldn't be default FSDirectory on 64bit Linux ater all?

Hi,
If the other suggestions for checking RAM don't help, please remove all JVM
parameters from command line like the special GC configuration:
jvm_args:
-Djava.util.logging.config.file=/var/lib/tomcat6/conf/logging.properties
-Djava.awt.headless=true -Xms4000M -Xmx4000M -XX:PermSize=400m
-XX:MaxPermSize=400m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.endorsed.dirs=/usr/share/tomcat6/endorsed
-Dcatalina.base=/var/lib/tomcat6 -Dcatalina.home=/usr/share/tomcat6
-Djava.io.tmpdir=/tmp/tomcat6-tmp
The first thing I looked at was if you have aggressive optimizations
enabled, but that's not the case, so you are fine :-)

Subject: Lucene killing JVM
Hi,
I recently upgraded to lucene 3.3 (from 3.0.3) and now my JVM keeps
crashing.
I noticed that it happens when I'm closing and reopening my index. It
doesn't
happen every time. Sometimes it works for days and sometimes it crashes
several times a day. Usually there is no exception in log files, only that
JVM dies
and error report file is created.
Index server is running on Tomcat 6, Ubuntu server 10.04, Sun JVM 1.6.0_26
Here's two examples of error report files:

Did anyone else experience something similar? Is this a known bug in
Lucene or
a JVM bug?
