java.lang.OutOfMemoryError:tomcat中超出了GC开销限制

我有一个Tomcat8实例，在windows机器上只运行jersey web服务应用程序。一段时间后（可能是数小时或数天），tomcat崩溃，留下以下日志：

看起来错误发生在web服务中，因为我可以在堆栈跟踪中看到

org.glassfish.jersey

但我不知道这到底是为什么，也不知道发生在哪里。也许我的一些服务消耗了很多内存，但我不知道是哪一个

是否有一种方法可以运行一些诊断以准确检测此错误的原因

使用jmap dump并尝试将占用大量内存的实例映射到您的代码gc花费的时间太长。这可能是因为交换。JVM进程使用的内存是否比实际可用内存多？@Thorbjørnravandersen GC overhead并不意味着GC花费的时间太长。这意味着JVM花费了太多的GCing时间，这可能是由于内存增长到了允许的最大限制。@JohnVint是什么触发了异常？花费的时间太长，收益太少。那么如何查看JVM正在进行垃圾收集呢？我的意思是，我能看看它收集的什么东西让它花费太长时间吗？
