Subject: 9i shared servers (dispatcher) hung


People could not connect via shared server - hung. So tried stopping the
dispatchers and restarting them. I did:
alter system shutdown immediate 'D000' ; 
alter system shutdown immediate 'D001' ; 

In alert log I see the following.
idle dispatcher 'D000' terminated, pid = (13, 1)

I do not see d001 stopping. If do a lsnrctl services it still shows
d001.

If do:
ALTER SYSTEM SET DISPATCHERS=''(address=(host=10.20.7.11)(proto
=tcp))(dispatchers=2)'';

Then lsnrctl services shows d000, d001 and d002. 

I ended up bouncing the database.  I had to do a shutdown abort since
shutdown immediate hung - probably due to dispatcher d001 getting stuck.
Any ideas on why a dispatcher would get stuck?
