Two 10g listeners at the same time

Hello all,

Twice this week the 10g listener spun a child process and hung all new connections to any database (10.2.0.2 on HPUX 11.11) This is what it looked like:

ps -ef ...

 oracle 21170 16606 0 13:57:00 ? 0:00
/usr/oracle/rdbms/10.2/bin/tnslsnr LISTENER -inherit
 oracle 16606 1 0 Aug 28 ? 83:26
/usr/oracle/rdbms/10.2/bin/tnslsnr LISTENER -inherit

The only way to fix this was to kill the processes (lsnrctl did not work) and start the listener again... No error messages were found in the listener.log.

Any help would be appreciated.

Thanks.
