Stms import queue is taking time to refresh

Hi Guru,

I am facing a stms_import issue. import queue is taking time to refresh and it is showing checking component. I could see the TRs already in Import queue from Se01 logs, but when refreshed to get the TR it is stuck here. Where RDD* job is event triggered.

Few days before we update our system.....Sap kernel --- 740 and sp level 07.

Please suggest..

Thanks
