我们正在使用带有jrockit 1.6 64位的Weblogic 10.3.2，我们的应用程序正在使用jboss seam框架。卡住的线程数正在稳步增加。这些卡住的线程只是等待，他们没有花费任何CPU周期。所有卡住线程的堆栈跟踪都是相同的，它们的状态是native_waiting。
上次java方法调用是com/sun/faces/application/ViewHandlerImpl.renderView(ViewHandlerImpl.java:186)。这是ViewHandlerImpl类的第186行的源代码;
WriteBehindStateWriter stateWriter =
new WriteBehindStateWriter(response.getWriter(),
context,
bufSize);
此电子邮件附有完整堆栈跟踪。这是一些卡住线程的堆栈跟踪;

你知道为什么这些线程在等待吗？...
