• Since your query doesn't return any columns of table mcpITEMTASKS, I would certainly remove the update lock !

    hence ... all your deadlock problems for this query case will vanish !

    The lock is on objectname="OBC.dbo.mcpITEMTASKS" indexname="2" which is indeed the object you only use for filtering purposes and do not return any data from.

    btw estimates for mcpitems are way off ( 63884 vs 450258 ) . it may come up with a better provisioned plan if you actually use the sproc paramters in your query predicates ( parameter sniffing ).
