Listener Hangs

We are running Oracle 7.3.4.5.0 on an IBM/AIX RISC System/6000: Version 2.3.4.0.0.  

Yesterday morning our LISTENER process hung. "ERROR: ORA-12203: TNS:unable to connect to destination". We resolved the problem using the following steps:

  1. Stop Listener using LSNRCTL utility
    (this hung - did not succeed in stopping the listener)
  2. Issue UNIX command kill -9 <process id> to kill the corresponding Listener process.
  3. Start the listener using the LSNRCTL utility

I checked the alert log and listener log. I found nothing in either file pointing to what the problem might have been. However, I did note that the listener.log file was 200 MB in size. Would the large size of the listener.log file contribute to the Listener hanging? This problem has occurred 6 to 8 times in the past couple of weeks. I do plan on starting a new listener.log file.  

Thanks,  

Sam Bootsma
