problems starting/stopping tomcat

[Astrid Wagner <As...@motorola.com>]

Hi ,
I use tomcat 4.1.24, jdk 1.4.0 and Apache 1.3 on Solaris 8.
After having developed and successfully run many servlets I now receive
a "port 8080 already in use problem" after I try to start tomcat.

I did not change any configuration and I do not think that the ports
are in use by any other processes (Apache uses a different port).
Could it be that while doing shutdown-startup sequences a process
has been left hanging (?).
When I replaced port 8080 by 8081 I was able to start tomcat but when I
called a servlet it said "8005" (port for shutdown) in use ?!
When I replaced also 8005 for test purposes the servlet hangs and I
could not see any error being logged (catalina.out, web appl log files, 
Apache log ...).

My question: how do I get more info about what ports tomcat still uses
for what ?
Any hint would be appreciated.
Thanks.
