该应用程序基本上是Apache Tomcat 8之上的Servlet，每3天崩溃到 n 天。最有趣的是，最后3次碰撞发生在下午1点30分+ 3到4秒。每次其他崩溃都发生在15,30,45或整整一小时。相同的应用程序在Windows 7上使用Java 7工作了几个月。
我找到了this报告，所以我检查了 / tmp 的可用空间，这里我有足够的空间。但是，下次我使用以下命令运行VM时
-XX：-UsePerfData
-XX：+ PerfDisableSharedMem
并且不再写 hsperfdata 文件，但问题仍然存在。根据{{3}}报告 PerfData 即使被禁用，也可能会在某种程度上被使用。
似乎是this：
void PerfLongVariant::sample() {
// JJJ - This should not happen. Maybe the first sample is taken
// while the _sample_helper is being null'ed out.
// assert(_sample_helper != NULL || _sampled != NULL, "unexpected state");
if (_sample_helper == NULL) return;
if (_sample_helper != NULL) {
*(jlong*)_valuep = _sample_helper->take_sample();
}
else if (_sampled != NULL) {
*(jlong*)_valuep = *_sampled;
}
}
我认为这里出现了问题：
*(jlong*)_valuep = _sample_helper->take_sample();
但我不确定在运行时使用了哪个实现：
piece of code似乎不太可能，因为我没有看到与 elapsed_counter 的连接，除了上面提到的崩溃时间现象。
/*
* helper class to provide for sampling of the elapsed_counter value
* maintained in the OS class.
*/
class HighResTimeSampler : public PerfSampleHelper {
public:
jlong take_sample() { return os::elapsed_counter(); }
};
inline jlong take_sample() {
return _gen->used();
}
和gSpaceCounter以及spaceCounters我的印象是Java内存池中其中一个池的大小在更新之前就会返回。这最终导致SIGBUS 7，内存访问不良。
我有什么选择？
上一次崩溃报告（已删除动态库）：
