我正在使用Java API嵌入式运行
以下是
neo4j 2.3.0-RC1，但它会在没有任何警告的情况下崩溃，我正在尝试找出问题所在。之前我曾成功地运行过这段代码，使用的是1.9.8。升级到2.0+需要添加事务、修改一些Cypher语法、启动Spring配置和少量其他更改。大部分代码仍然相同，并且功能正确，通过单元测试和集成测试进行了确认。启动引擎后，它会以相当恒定的速度添加新的节点。以下输出显示在290分钟后发生了神秘的崩溃。它似乎总是会发生，有时在2小时后，有时在5小时后。而使用1.9.8就没有发生过这种情况。JVM是用./start-engine.sh > console.out 2>&1 &来运行的。而start-engine.sh的操作行是：$JAVA_HOME/bin/java -server $JAVA_OPTIONS $JPROFILER_OPTIONS -cp '.:lib/*' package.engine.Main $*
以下是
console.out的最后几行。17437.902: RevokeBias [ 112 6 5 ] [ 20 6 27 43 26 ] 1
17438.020: RevokeBias [ 112 3 9 ] [ 5 0 5 0 0 ] 3
17438.338: GenCollectForAllocation [ 113 2 2 ] [ 1 0 11 4 32 ] 2
17438.857: BulkRevokeBias [ 112 3 13 ] [ 0 0 28 6 2 ] 3
./start-engine.sh: line 17: 19647 Killed $JAVA_HOME/bin/java -server $JAVA_OPTIONS $JPROFILER_OPTIONS -cp '.:lib/*' package.engine.Main $*
没有堆栈跟踪，也没有其他错误输出。
这是来自/mnt/engine-data目录下messages.log的最后几行。

在崩溃之前，一切看起来都很正常，而崩溃则完全出乎意料。
messages.log中有大量其他数据，但我不知道要找什么。
