Snapshot Synchronization Failing

[Edenost]

Hi there,

 

I have a fairly new SCOM install up at the moment.

It consists of:

 

2 Management Servers

2 Gateway servers on other domains using certificates

1 SQL Server with two instances, one for OperationsDB and one for WarehouseDB.

 

Ever since I installed it a couple of weeks ago, I get the following error every now and then, and it can last for up to 2 days at a time:

 

OpsMgr Management Configuration Service failed to execute 'SnapshotSynchronization' engine work item due to the following exception

Microsoft.EnterpriseManagement.ManagementConfiguration.DataAccessLayer.DataAccessOperationTimeoutException: Exception of type 'Microsoft.EnterpriseManagement.ManagementConfiguration.DataAccessLayer.DataAccessOperationTimeoutException' was thrown.

at Microsoft.EnterpriseManagement.ManagementConfiguration.DataAccessLayer.DataAccessOperation.ExecuteSynchronously(Int32 timeoutSeconds, WaitHandle stopWaitHandle)

at Microsoft.EnterpriseManagement.ManagementConfiguration.CmdbOperations.CmdbDataProvider.GetConfigurationSnapshotNextBatch(SnapshotProcessWatermark watermark)

at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.TracingConfigurationDataProvider.GetConfigurationSnapshotNextBatch(SnapshotProcessWatermark watermark)

at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.SnapshotSynchronizationWorkItem.TransferData(SnapshotProcessWatermark initialWatermark)

at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.SnapshotSynchronizationWorkItem.ExecuteSharedWorkItem()

at Microsoft.EnterpriseManagement.ManagementConfiguration.Interop.SharedWorkItem.ExecuteWorkItem()

at Microsoft.EnterpriseManagement.ManagementConfiguration.Interop.ConfigServiceEngineWorkItem.Execute()

Now when this is happening, I also get a whole bunch of others:

Once the original error above clears, the others also resolve, so I'm only interested in said error I'm assuming.

I have been running the following query on the OperationsDB on SQL:

Select WorkItemName, b.WorkItemStateName, ServerName, StartedDateTimeUtc, CompletedDateTimeUtc, DurationSeconds, ERRORMESSAGE

from cs.WorkItem a , cs.WorkItemState b

where a.WorkItemStateId= b.WorkItemStateId

and WorkItemName = 'SnapshotSynchronization'

Which returns the following:

On one which was succeeded, the day before, the time shows 302.

I have increased the timeouts on the config files on both Management servers and restarted the services (even the servers themselves), but still nothing helps.

Pulling my hair out with this a bit!

All machines are Windows Server 2012R2.

We do run them on VMWare with DRS enabled, but they haven't migrated for some time, so it's not a host/network thing as far as I can see.

OpsMgr is running as normal mostly, still monitoring things and reporting, but I cannot add new objects to monitor until this clears.

The Management Servers and others also show this in the even log:

"OpsMgr's configuration may be out-of-date for management group <Management Group>, and has requested updated configuration from the Configuration Service.", but I don't see successful update of the cookie until this issue resolves itself.

Any help is much appreciated!

Cheers

Does anyone have any ideas? This is still happening. It happened twice over the weekend, each lasting around 18 hours, and it's just happened again this morning

Hi,

i have the same Issue and for me it is caused by the DELL ManagementPack.

If you have more then 300 Objekts Discovered it causes those Issues.
