The Dashboard uses the managedobjects.com domain name for a reserved user account. If any Dashboard user account has the user name containing “managedobjects.com”, the following error occurs:
2007-05-02 10:13:02,670 ERROR com.mosol.liferay.authenticator.MOAuth - Unable to synchronize user managedobjects.com.1001 com.liferay.portal.UserIdException at com.liferay.portal.service.impl.UserLocalServiceImpl.validate(UserLocalServiceImpl.java:1460) at com.liferay.portal.service.impl.UserLocalServiceImpl.addUser(UserLocalServiceImpl.java:194) at sun.reflect.GeneratedMethodAccessor513.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:280) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:187) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:154) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:107) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:176) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:210) at $Proxy7.addUser(Unknown Source) at com.liferay.portal.service.UserLocalServiceUtil.addUser(UserLocalServiceUtil.java:94)

If the Dashboard Web server stops while writing data, an exception can be thrown that appears as a SocketException or broken pipe error. This exception is not a true error because no data was lost and the Dashboard will recover itself and resume normal operations.
For more information, see Section 12.6, Performing System Recovery.
The following is a sample of the code that might appear for this type of exception:
