mongod崩溃（终止于信号5）

Question

我配置了一个mongodb的capped集合，容量超过3G，在多次mongod崩溃后，但mongd.log.Howerver没有出错linux abrt已经核心转储mongod的，从核心转储信息如下：

我MongoDB是2.4.1，在CentOS的6.3,16G内存和8cpus运行。 任何人都可以帮助我？非常感谢。

提到的内存不足的错误使我怀疑，这可能是这个bug（V8内存泄漏）的发生：

https://jira.mongodb.org/browse/SERVER-9230

可以升级到2.4.2+，看看错误仍然发生在你​​身上？
