We're trying to set up publisher (rendering/deploying) filtering in the Tridion MMC.

When we set up multiple publication targets in the filtering, we get following error upon restart of the publisher service:

Sequence contains more than one matching element

Component: Tridion.ContentManager.Publishing Errorcode: 0 User: ****

StackTrace Information Details: at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable1 source, Func2 predicate) at Tridion.ContentManager.Queuing.QueuingEngine.AddMissingFilters(IList1 listQueueFilterData) at Tridion.ContentManager.Queuing.QueuingEngine.OpenQueue(Int32 queueId, Int32 configurationId) at Tridion.ContentManager.Queuing.QueuingEngine.CreateQueueConsumer(Int32 queueId, Int32 configurationId) at Tridion.ContentManager.Publishing.Publisher.QueueConsumerHandler.DoWork()

setup in MMC

Someone had a similar issue and knows how to fix it? It's a 2011 SP1 server, HR + other hotfixes installed.

    Not one I've seen before. The 'AddMissingFilters' and 'Sequence contains more than one matching element' error messages would seem to suggest that there is a problem getting the default values for the three filters that you have (correctly) not entered. Not a solution, but adding values to these (e.g. Priorities='2', Publications='tcm:0-99-1' & Hostnames='yourCmsServer') and seeing what happens could give you more information to go to Tridion Support with (or add here).

There's a hotfix for the given problem (77810), but it's supposed to be included in 2011 SP1 HR1. It's best to contact customer support

  • this was indeed (initially) included by the HR1, but somehow the GAC dll of tridion.contentmanager.queuing got overridden when installing some event system stuff in the GAC. Thx for the help! Jul 4, 2013 at 5:51
