Hello,
I have a problem with my little CORBA-Servlet.
Allways I get this error:

I use: Tomcat 6.0.26 on Linux JVM: 1.6.0_20-b02
At first sight, it doesn't look as if this is a Tomcat issue. It seems
more of an issue within your servlet.
Is this servlet opening its own connection to something else?
If yes, then you probably forget to close this connection when you are
done with it, and they accumulate until the OS tells your process that
it has too many open sockets at the same time.
Doing a "netstat -an" would probably provide more information.
If you are under Unix/Linux, you can also try "lsof", but only studying
the options is already quite a challenge.
