I think there is a problem in usp_CALLMAN_UPDATE_ADVISERS first look at this query execution plan and if it need any index. And

it is a query like this

Maybe you can use with(nolock) hint in this select and then update and check index fragmentation

AND ASD.[Status] IN (2<c/>4);

03/26/2013 12:20:01,spid23s,Unknown,AND ASD.DateTo > @CurrentDate

03/26/2013 12:20:01,spid23s,Unknown,WHEREASD.DateFrom < @CurrentDate

03/26/2013 12:20:01,spid23s,Unknown,ASD.AdviserID = ADV.AdviserID

03/26/2013 12:20:01,spid23s,Unknown,INNER JOINCallManager.dbo.CallMan_AdviserStatusDatesASDON

03/26/2013 12:20:01,spid23s,Unknown,FROMCallManager.dbo.AdvisersAvailabilityADV

03/26/2013 12:20:01,spid23s,Unknown,SETADV.[Status] = ASD.[Status]

Thanks very much for your input.

I have taken a look at that sp and notice that the isolation level is set to Serializable ! I also notcied this in the error log provided.

Would it be advisable to change it to Read Comiited ?
