netstat -a localhost to localhost

[chad kellerman <ck...@alabanza.com>]

Hello everyone,

    I have a redhat 6.2 machine ( I know a little behind the times, but it 
works very well)  with Tomcat 4.0.1 running with mod webapp both securely and 
non-securely.  

    I little question.  Whne I run a netstat -a I notice many connection from 
and to localhost  from the ports I designated in my server.xml configuration 
file.  Is this normal?

    Here is a little output:

tcp        0      0 localhost:2327          localhost:8008          
ESTABLISHED
tcp        0      0 localhost:8008          localhost:2326          
ESTABLISHED
tcp        0      0 localhost:2326          localhost:8008          
ESTABLISHED
tcp        0      0 localhost:8008          localhost:2325          
ESTABLISHED
tcp        0      0 localhost:2325          localhost:8008          
ESTABLISHED
tcp        0      0 localhost:8008          localhost:2324          
ESTABLISHED
tcp        0      0 localhost:2324          localhost:8008          
ESTABLISHED
tcp        0      0 localhost:8008          localhost:2323          
ESTABLISHED
tcp        0      0 localhost:2323          localhost:8008          
ESTABLISHED
tcp

     I find it odd that the server ( being idle ) would have that many 
localhost connections ESTABLISHED.  This is not public yet so there are not 
too many requests yet.

     I am thinking it could be a java thing.  In my catalina.sh I have 
CATALINA_OPTS set with  -Xmx64m -Xms32m.  Maybe tomcat will open as many 
connections as it can with the amount of memory I allow it???

Any help would be appreciated.

Thanks for all the help,
