Question

我在Windows主机上安装了64位Tomcat 7.0.27，并将Pervasync数据同步服务器部署到Tomcat，以将Android平板电脑上的SQLite DB与中央Microsoft SQL服务器同步。它起初效果很好，但有时候Tomcat会随机崩溃。从Tomcat日志中我看到了：

这真的是JVM中的错误还是其他什么？

Tomcat崩溃往往是由JNI libs引起的。 Pervasync是纯Java。首先要检查的是你是否加载了Tomcat Native库。看看Catalinna * .log中是否有以下内容：

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.

您下载的二进制文件可能与您的硬件不兼容。重新编译lib或切换到非本机 - 从Tomcat路径中删除lib。

有关Apache Tomcat Native库的更多信息，请查看http://tomcat.apache.org/native-doc/。

当我将Android SQlite与MS SQL服务器同步时，托管同步服务器的Tomcat经常崩溃
