I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi,
one simple reason for this could be that the listener.log file has reached a size limit (ulimit -n) or that its filesystem is full.
It's usually $ORACLE_HOME/network/log/listener.log.

... one other, not uncommon reason could be that the listener tries to connect to a busy port.
You could check this by comparing your listener.ora settings with 'netstat -an'  output.

I think you should post your listener log file, so we can find more detail in your problem. May be you lost config in tnsname.ora, example :

listener=
        (DESCRIPTION=
                (ADDRESS=(PROTOCOL=tcp)(HOST=test)(PORT=1521))
            (CONNECT_DATA=
                (SID=listener) --or depend on your system
            )
        )
