I think your query is related to periodic TAU, once the periodic TAU timer expires, UE initiates TAU.
As per my understanding, there is no interrupt since TAU is a NAS procedure and handover is S1-AP. Even though handover procedure is in progress, there is no impact on periodic TAU procedure.

Please correct me if I am wrong or misunderstood your query.

When target eNodeB is not able to allocate resource for all the bearers which comes as part of Handover Request message, it sends handover request ack with partial success since "E-RABs Failed to Setup List" is present in HOReqAck message.
What MME or source eNodeB does in that case ? Does any action taken by MME for the E-RABs which failed to setup at target eNodeB or some other actions taken ?
