Java应用程序随机崩溃

我们的应用程序随机崩溃。平台是RedHat Linux，java版本是jdk 1.6_17。它是一个基于swing的应用程序，有很多本机代码。这种行为很随意。有时它会在几分钟内崩溃，有时会在几个小时后或长时间运行后崩溃。我发现pid文件有时指向发生崩溃的ReferenceHandler线程。这是在自由运行期间。有时它在malloc操作期间在EDT中崩溃，而每次我们的代码都不涉及。我将感谢任何帮助或线索在这方面，因为这并不总是重复

提供以下几项碰撞信息：

间歇性和不可预测的崩溃表明可能存在线程问题。还有一种可能是JVM错误，您是否尝试过使用最新版本（如果是JDK6）运行？一点也不可能，较旧的Java 6运行时版本有大量已修复的本机崩溃错误。这个问题发布得太早了，当然你首先要尝试用更新的补丁版本来重现，以排除答案是“这是运行时的一个bug，需要升级”。谢谢你的回答。我也在考虑尝试使用Java6Update45，但由于与我们的软件/及其所涉及的平台/官僚机构的性质相关的某些限制，我还没有尝试过，但很快就会尝试。
