Hi DBA's

Our production database has a tablespace with the following schema:

CREATE TABLESPACE IRD_DATA_LARGE
    DATAFILE 'E:\ORANT\DATABASE\USR1PROD.ORA' SIZE 128472K AUTOEXTEND ON NEXT 2K MAXSIZE UNLIMITED
    LOGGING
    DEFAULT STORAGE(INITIAL 100K

                    NEXT 100K
                    MINEXTENTS 1
                    MAXEXTENTS 121
                    PCTINCREASE 1)

    ONLINE
    PERMANENT This tablespace has only 2MB of free space available. The fragmentation index is 58.7
The largest table is 29MB and has 5 extents. I've observed some segments with Max Extents different than 121 which is the default and how most of the segments were created. I know I need to add another datafile, however, I'd like to find out what would happen if a segment requested another extent that was larger than the available free space in the tablespace. Since AUTOEXTEND is enabled is there a possibility that this situation could cause the tablespace or instance to go offline or crash?

Thanks for your comments and advice!
