lsnrctl doesn't really stop the listener

I have been trying to stop the listener through the usual way:

LSNRCTL> stop
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC))) The command completed successfully

But very often, the listener stays up. I can see it with 'netstat -a', I can telnet into port 1521 and I can run sqlplus from another machine. In those cases in which the listener refuses to die, I can see that there are two processes talking to each other through that port (with netstat -ap): tnslsnr and ora_pmon.

I don't have my 10g available right now, so I can investigate this matter there.

Is this zombie-like behavior normal? Can some of you folks check whether your listeners stay up after they are stopped?

Should I just kill 'tnslsnr' by hand when lsnrctl fails?
