我的应用程序在将其迁移到64位后开始崩溃。在我们的生产Linux服务器上每2-3天发生一次崩溃。我们正在使用jdk1.6.0_15-x86_64。当我的应用程序使用Xalan转换器将XSLT转换为HTML时，崩溃发生在同一个地方。
我已经确认这不会发生在我们的32位服务器上，并且当应用程序不执行XSLT到HTML转换时不会发生这种情况。所以只有当转换发生在64位服务器上时才会发生。
任何帮助都将受到高度赞赏。

您的permgen似乎已损坏，这可能是因为您的代码试图加载库。我怀疑通过以下代码加载的库可能与64位JVM不兼容。
在向JVM提交错误之前，我会在程序中检查以下代码行，这似乎是罪魁祸首。
com.ente.hrxml.resume.HtmlConverter.toHtml(Lorg/jdom/Document;)Ljava/lang/String;+49

我建议增加perm gen空间（-XX：MaxPermSize）并在其上启用GC（-XX：+ CMSPermGenSweepingEnabled） - 40M并不多！如果要加载大量库，我还建议启用类卸载（-XX：+ CMSClassUnloadingEnabled）。请注意，如果你确实有内存泄漏，这只会让你在崩溃之间有更多的喘息空间，你仍然需要解决根本原因。
