我目前正在研究我在Jetty中运行的程序。有时候（比如两周一次）它崩溃了JVM，我不确定为什么会这样。我唯一的猜测是它可能与记忆有关。 由于错误已经有一段时间了，我已经将JRE从8.0_66更新到8.0_77了。
它生成一个hs_err_pid日志文件：

我发现这可能与内存有关，应该检查堆。 在这个日志中，这似乎是53％已满，但我也发现了10％和99％的日志。 此外，堆栈跟踪在这些日志中总是不同。
在下面某处，我在GC之前发现另一个（较旧的？）堆，实际上表示100％使用。这是否意味着它与内存相关并增加了码头的内存应该解决这个问题？

我尝试过的更新内容：
到目前为止，我已经检查了内存没有任何问题。
我将JRE更新为8.0_92。
我设置参数-Xms1g -Xmx2g。
但似乎无法解决问题，因为这次运行程序后3秒又发生了另一次崩溃：http://pastebin.com/jjEVm09V
