I can think of one recent change for iscsi-target wrt to session referencing counting that could be causing this type of regression in lio-core.git HEAD and mainline v3.4-rc1, but I don't see how it would effect v3.2.x stable code.. Is there anything else special about the work-load and/or configuration required to trigger this bug you've noticed during in your testing..?
