I'm not a DBA but we had this problem with 7.0.16. When we used to fresh install ORACLE the optimum size of the rollback segments were not being set, Extents get allocated when insert, delete etc are performed, but they weren't being de-allocated after the commit has been made,
What we did ,was we offlined the rollback segments, dropped them and recreated them with the optimum size specified, Now the size of the RBS is your transaction size dependent, you'll have to figure out what the initial, next , optimum size would be, Or you might want to increase the size of your Rollback segments. For details refer to ORACLE's DBA Guide Documentation.

Hope this helps
