All Management Servers Resource Pool Unavailable Error
I install 2012 and add agents, everything is fine for about 2 weeks, then I get a "All Management Servers Resource Pool Unavailable" error condition and cannot recover from it. I have built 2 totally seperate envinments now and each time they have literally broken without doing anything...we let them sit and monitor without making any changes then we get this error and cannot get around it. One MS as an all in one server. SQL 2008R2 30 agents in our test domain. What is going on here?

Thanks GMan. The error instantly comes back and I'm unable to do much with SCOM after that. It seems everything is broken for no real reason. I've spent HOURS trying to resolve. 2 new builds, same results after letting them just "sit" without any further customization. I will NOT install 2012 in production after seeing this happen twice now. I opened a case with MS and they would not help since I was not a beta customer. I do not trust 2012 at all as stable. I'll wait for final RTM I guess. Sad face.

Yeah, this is in a test domain, my env is too large to play russian roulette with beta bits. I'm reinstalling a third time today. :D

Adding myself to this thread in case MS ever answers. I never noticed this happening in my RC environment but it is happening with the "production" build. I have 4 servers in Hyper-V with a remote SQL instance. An answer from Microsoft would be great. This is holding up the roll out.

I cannot deploy 2012 with this bug...If it didn't shut down monitoring and email alerts I could live with it but being that notifications STOP and you are blind to the meltdown this is a huge showstopper. SCOM is 100% broken when this alert happens and you get no Notification of it.

In digging a little deeper into the Operations Manager application logs I noticed an error 29181. It points to the DB being full. I believe that Operations Manager sets auto growth to none by default on the db install. At least it did for me. I used SQL Server Management Studio and set the growth on the Operations database to unrestricted. We'll see if that helps. Here is the alert context for your reference. System.Data.SqlClient.SqlException (0x80131904): Sql execution failed. Error 1105, Level 17, State 2, Procedure WorkItemMarkCompleted, Line 68, Message: Could not allocate space for object 'CS.WorkItem'.'PK_WorkItem' in database 'OperationsManager' because the 'PRIMARY' filegroup is full.

When I received this error, it was because my MGMT server was in maint mode. I put it in maint mode this morning to do patching on it, and i guess i set the time frame for longer than i thought. Once I took the mgmt server out of maint mode, I got flooded with about 25 alerts at once.

We have had stability for a few days. The server seemed to be eating RAM, it seems there is a known memory leak issue with the SCOM 2012 console which had been left open on the server. I have been using the web console and RAM usage is a lot lower and have had no "All Management Servers Resource Pool Unavailable" for a few days. Fingers crossed.

We're getting this same problem in RTM. Fine for several weeks then all of a sudden everything is broken. Any ideas??? In addition to this, we're getting flooded with Event ID 20000's.

Hey everybody ! I have the same problem and i just resolve it by re-enter the credential of the scom manager and administrator in the Run As Accounts Settings. Tell me if for you it's ok ! Regards !

It seems to pop up if you reboot your remote SQL box hosting your OM DB. Then a flush of your MS servers HS cache helps to remove it. It seems to be a come and go kind of error that I cannot pinpoint an exact cause/fix for. DB Connectivity is definitely in the mix. Also, MS recomends these 2 Reg Hacks for this issue for 'all in one' boxes: HKLM\SYSTEM\CurrentControlSet\services\HealthService\Parameters\PoolManager /v PoolLeaseRequestPeriodSeconds /t REG_DWORD /d 600 /f reg add HKLM\SYSTEM\CurrentControlSet\services\HealthService\Parameters\PoolManager /v PoolNetworkLatencySeconds /t REG_DWORD /d 120 /f My all in one BCP environment has been doing fine, but displayed this behavior AFTER updating with CU2 last night. These reg hacks plus a health service cache flush took care of it. Thank you for posting this. Perhaps something needs to bake a little more.

Hi, I have this problem too, i need to reboot the SCOM server and this resolve the issue. However after a few days the problem would come back again, is there a permanent solution to this problem? Thank Li Liang
