List Item Timeout Issue

Question

On one of our production Sharepoint Sites we have a ListItem that will not load it's details. It simply times out and throws an exception with a GUID. The Log file indicates that:

System.Threading.ThreadAbortException: Thread was being aborted. 08/25/2011 13:14:04.03 w3wp.exe (0x1DB4) 0x1184 SharePoint Foundation General xxpm High Unable to execute query: Error 0x80131530 66c92e39-0443-40b0-bef8-d9d74e292fbd

I am asking for Read access to all databases on our Sharepoint server so that I can see how long the SQL command (shown in the logs) takes to execute. It's an absolute massive query.

How does one go about troubleshooting a Listitem that is having SQL Server timeouts?

Answer 1

• Does the item have a it's own ACL's, i.e. it's security has been "decoupled" from the parent list?
• Does it have a lot of lookup columns?
• Is Project Server installed (or deinstalled) and is sharepoint assuming it should do some extra project server stuff it shouldn't?
• Are there any audiences assigned to the item?

An item level query will only grow this big if it needs to do some joins for say ACL's, lookups etc. I.e. the item references other stuff instead of having all it's data "self-contained".
