Hi We are using SCOM R2 with CU4. When we checked in opsmgr log in RMS we are getting every minute 20 Event id:1103 warnigs. Event Type: Warning Event Source: HealthService Event Category: Health Service Event ID: 1103 Date: 7/14/2011 Time: 11:24:10 AM User: N/A Computer: IND-AP142 Description: Summary: 1 rule(s)/monitor(s) failed and got unloaded, 1 of them reached the failure limit that prevents automatic reload. Management group "MG_IND". This is summary only event, please see other events with descriptions of unloaded rule(s)/monitor(s). For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Help us to resolve the issue. Regards Donald D'souza

Before this summary warning you could find a detailed warnings (w/Event Source = Health Service Modules) for every failed rule\monitor. Can you post it? http://OpsMgr.ru/

Look for others aroundthe same time - try restarting the health service to get the sequence to repeat. This is a summary error and does not have enough detail to troubleshoot. Also, look at the failed workflow report on this agent - that may give you a clue which monitor has failed.Microsoft Corporation

It looks like a group calculation rule is failing because by the time it goes to insert the group members, one or more of them has been deleted.Microsoft Corporation

Hi Dan Thanks for information. I am unable find the Group type name: BlueService_729b49f2281946ec892b71e1d57fdd71 .Is it possible to find out which group or which MP throwing this error. Regards Donald D'souza

It's definitely a group that was created with the console tools - so you or someone with admin permissions would have created it. If the things it is looking for have been deleted (an MP that is deleted?) then the group is probably a hold-over, and can safely be deleted. Microsoft Corporation
