Ibm mobilefirst MobileFirst 7.0在服务器场模式下上载应用程序时；“无反应”；收到错误

环境详情： OS RHEL 6.8 64位 IBM MobileFirst Platform服务器版本-7.0.0.00.20160526-2153 Project WAR版本-7.0.0.00.20161114-0240 应用程序版本-7.0.0.00.20160526-2153 IBM Websphere Liberty Verison-8.5.5.4 Java-IBMJRE 1.7.0

为jndiName=“ibm.worklight.admin.serverid”、farm_成员_1和farm_成员_2创建了一个带有uniques值的场配置。 开始时，两台服务器都会在messages.log中显示以下内容：

[1/8/17 18:53:14:313 CST] 00000034 SystemErr R 1111  WorklightManagementPU-db2  INFO   [LargeThreadPool-thread-10] openjpa.Runtime - Starting OpenJPA 1.2.2

[1/8/17 18:53:14:315 CST] 00000034 SystemErr R 1113  WorklightManagementPU-db2  INFO   [LargeThreadPool-thread-10] openjpa.jdbc.JDBC - Using dictionary class "org.apache.openjpa.jdbc.sql.DB2Dictionary" (DB2/LINUXX8664 SQL10053 ,IBM Data Server Driver for JDBC and SQLJ 4.17.29).

几乎每次将应用程序上载到运行时，服务器2（服务器场成员）都会变得无响应（Web控制台主页-->运行时-->服务器场节点）。发生这种情况时，服务器2会更新所有资源，就像重新启动一样，从运行时加载所有应用程序和适配器。加载完所有应用程序后，将再次显示以下错误：

这是这种配置的常见问题吗？如果没有，有什么办法可以避免吗？

这些都是警告，可以安全地忽略。这些由OpenJPA软件包记录。

服务器的无响应状态如何，这是正常行为吗？
