(FAQ)Server1经常被重启，导致EAS Cloud操作过程中频繁出现异常
原因分析：
步骤 1 查看server1日志文件server.trace，发现多次启动记录，没有停止记录，说明该实例出现过进程消失这样的严重故障。

步骤 2 检查server1下的WebSphere日志native_stderr.log，发现有natvie OOM异常，异常发生时JVM heap还有很多可用内存。
JVMDBG001: malloc failed to allocate 12288 bytes, time: Mon May 10 15:51:36 2010
**Out of memory, aborting**
*** panic: JVMCL052: Cannot allocate memory in initializeHeap for heap segment
JVMDG217: Dump Handler is Processing Signal 6 - Please Wait.
步骤 3 操作系统errpt日志显示，WAS发生异常，并产生了core文件。

步骤 4 SystemOut.log显示无法创建更多的线程，判断很可能是更新导致HTTP线程过多所致。

解决方法：
启用NAP来负责更新。
集群环境NAP默认是自动启动的，在管理控制台有一个“网络代理”页签，默认端口号是8080。通知所有客户端改用8080作为更新端口。
