Problem with listener process

479855Jan 2 2006 — edited Jun 9 2006

Hi all,

First, happy new year for everybody.

I'm under Linux and i have a problem with a listener process in Oracle 10g 10.1.0.3.
From time to time, my listener process hang-up and it becomes impossible to obtain a Oracle connection.

With unix 'ps' command, i can see strange process.
# ps auxw | grep lsn

... etc ...
root 9310 0.0 0.0 1612 472 pts/2 S 08:35 0:00 grep lsn

If a stop and restart the listener, i don't have any more problem.
I suspect OEM agent because each time i noted the problem, the agent was running .
What occurs? Thanks for your help.
