What does thir error mean ?

Hi, we have Oracle Workgroup Server 7.3.2 running under Solaris X86 2.5.1 It has been working fine for over a week and all of a sudden I am getting the following error when running an update statement :

update test_table
*
ERROR at line 1:
ORA-01562: failed to extend rollback segment number 4 ORA-01650: unable to extend rollback segment R03 by 64 in tablespace RBS

I am fairly new to Oracle and would appreciate any help that you can provide. Thanks.
