Hi everyone, A few days ago, I created a new subscription that notifies when alerts are generated from specific rules. Originally, I had added myself and our Dev team to receive the notifications. However, I recently removed myself from the notification subscription, but it is still e-mailing me. Through the OpsMgr shell, I've looked up the notification subscription ID contained in the e-mail and verified that the notification subscription itself only contains the e-mail address of the Dev team, so I'm not sure how/why I am still being sent e-mails. I remember seeing something similar to this in an earlier version of SCOM (I think it was in the early SP1 days), but this is the first time I'm seeing this problem with R2. Our environment is running R2 with CU3. Does anyone know why this is happening or has anyone else seen this problem? Thanks for your help!

Does the subscription include a distribution group? If so, are you in the distribution group? have you restarted the server (just something to try - get it to clear it's cache)Microsoft Corporation

The notification that is sent to the Dev team is a disto group, but I'm non part of that distro group in AD, so I shouldn't receive their mail. I haven't restarted the server yet (it's a clustered RMS, so I'd just perform a failover to the other cluster node), but I'm wondering why the cache would get into a bad state in the first place. Recently, I've also been noticing that at some point SCOM starts generating events in the event viewer stating "Operations Manager had discarded 30 items in management group...because no valid route exists at this time..." When I've seen this message, I've noticed that new agent installs all show up in the console, but all display as "Not Monitored." Only after I restart the SDK service does everything start working properly again. So it's possible that this might be another symptom that might be solved by restarting the SDK. Is there any further troubleshooting that I can do to determine what exactly is causing this problem in the first place - that requires a restart of the SDK service to start working again? Thanks!

Hi, "Recently, I've also been noticing that at some point SCOM starts generating events in the event viewer stating "Operations Manager had discarded 30 items in management group...because no valid route exists at this time..."" What is the event ID? (more than one event ID? )Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Ahh. You have a management group health problem. You need to get agent communications healthy and non-gray agents in order before you add any more agents.Microsoft Corporation

Yes first get to a steady state before making changes like new agents and so on. Best to first check for the health of the management servers and from there check if you have any grey agents and fix those.Bob Cornelissen - BICTT (My BICTT Blog) - Microsoft Community Contributor 2011 Recipient

Thanks everyone for all your help. I've read through the articles and also run the SQL query found here: http://social.technet.microsoft.com/Forums/en/systemcenter/thread/a7a21192-92f2-477f-a268-e1c355df0e98 However, I haven't found the solution yet. The below event keeps showing up in the EV on the RMS with Event ID 21042. The event appears exactly every 10 minutes. "Operations Manager has discarded 32 items in management group SCOM, which came from scomdb02. These items have been discarded because no valid route exists at this time. This can happen when new devices are added to the topology but the complete topology has not been distributed yet. The discarded items will be regenerated." I verified that all agents (Monitoring > Operations Manager > Agent Health State) show up with all green checkmarks. However, most of the custom Web Application monitors that I created (Monitoring > Web Application > Web Applications State) are showing up as Not Monitored (these were all previously working properly). It seems as every few weeks, some strange problems start happening that I can't explain and they are intermittent (Notification Subscriptions not working as expected, new agent installs show as not monitored, Web Applications show not monitored, etc.). Restarting the SDK service typically fixes the problem or deleting the Health Service State folder on the RMS (and restarting the Health Service) typically corrects the problem. However, I think it's rather strange that such a powerful monitoring product needs its services restarted every few weeks now. I wish there were a way to see what is causing this problem to start happening that needs these restarts to happen. Anyone have any other ideas what I could look for? Thanks!

Hi Christopher, we have the same problem with the subscription issue. After someone was deleted from the notification subscription. He still gets notifications emails about SMTP setup. Do you already found a solution for it? If so please share or we have to dig further. The frustration problem is where to look, i can imagine in some dark places of scom a discription entry isnt deleted but where? If i run into a solution i will post it here.
