我在我的 Windows 主机上安装了 Tomcat 7.0.27 64 位，并将 Pervasync 数据同步服务器部署到 Tomcat，以便将 Android 平板电脑上的 SQLite DB 与中央 Microsoft SQL 服务器同步。它最初运行良好，但有时 Tomcat 只是随机崩溃。从Tomcat日志中我看到了这个：

#

这真的是JVM中的错误还是其他什么？

Tomcat 崩溃通常是由 JNI 库引起的。Pervasync 是纯 Java。所以首先要检查的是你是否正在加载 Tomcat Native 库。查看 Catalinna*.log 中是否有类似以下内容：

Apr 02, 2013 3:07:51 PM org.apache.catalina.core.AprLifecycleListener init
INFO: Loaded APR based Apache Tomcat Native library 1.1.27 using APR version 1.4.6.

也许您下载的二进制文件与您的硬件不兼容。重新编译库或切换到非本机 - 从 Tomcat 路径中删除库。

查看http://tomcat.apache.org/native-doc/了解更多关于 Apache Tomcat Native 库的信息。
