08-13-2007, 10:40 PeterBauwens Joined on 04-02-2007 Posts 6 Eventing Service timing out In our TFS setup the Scrum Eventing Service often times out while updating work items. I've been reviewing the messages in the Event Viewer and tracked back on several of the workitem id's i found in there. There seems to be no obviuous reason why it would time out. At first I thought it might be caused by PBI's having a lot of SBI's but it also happens with PBI's having only 2 or 3 linked SBI's. Any idea why updating a PBI with 2 SBI's would take longer than 2 minutes? When updating the PBI's and SBI's using the ScrumConsistencyCheck tool it never occurs... Thx in advance, Peter      Report

In a previous post (http://scrumforteamsystem.com/cs/forums/989/ShowPost.aspx), you mentioned that you unsubscribed and resubscribed the event when you moved server - do you have the steps used for this as the out-of-the-box-installation limits the event to only fire to a limited set of actions?    Report

The event was correctly registered, i've put the filter in the rtf document as well. Thx in advance    Report

01-17-2008, 9:04 Stuart Preston Joined on 03-25-2006 Posts 225 Re: Eventing Service timing out For all those who find this thread and by way of an update on this issue: Background: Each "Sprint Backlog Item" update will cause a new request to our webservice initiated by TFS. The webservice itself connects to TFS, using the context of the saved work item (passed in by TFS) to evaluate the linked items. If a Product Backlog Item is found, all the links of that Product Backlog Item are evaluated to see if there are any tasks with Work Remaining - if so, the totals are added up and the "parent" Product Backlog Item is updated. Technical overview: The call to create a new instance of the Server object is rather expensive, and as has been reported a couple of times with larger installations (e.g. corporations running multiple concurrent projects) - a resource limit can be reached prior to the IIS Application Pool being recycled naturally causing exceptions that are surfaced from within TFS. Workaround: For those people who experience this issue, we recommend disabling the existing subscription with the following command: "C:\Program Files\Conchango\Scrum for Team System\tools\EventSubscriber.exe" "/U" "/TFSName" "http://[TFSServerName]:8080" We then recommend to schedule the Work Remaining Consistency Checker tool (see http://scrumforteamsystem.com/cs/forums/1108/ShowPost.aspx) to ensure that Work Remaining is synced occasionally (e.g. every 15 minutes). This can be scheduled for individual projects and offers a better performance profile overall for larger projects. We have rewritten this service for Scrum for Team System v2.0 and a decision has been made not to back port it for earlier versions. Whilst we have tested and seen dramatic improvements overall, we would be grateful for any feedback from the community on the performance of the new version. The beta version of Scrum for Team System v2.0 can be downloaded from our forum at http://scrumforteamsystem.com/cs/forums/default.aspx?ForumGroupID=2    Report
