Threads and SocketException

OK, I'm using tomcat and a sevlet to launch a background process in a 
separate thread. It seems to launch just fine, but after it runs for 
maybe 30 seconds it dies, spitting out this error:

java.net.SocketException: Connection reset
    at java.net.SocketInputStream.read(Unknown Source)
    at java.io.BufferedInputStream.read1(Unknown Source)
    at java.io.BufferedInputStream.read(Unknown Source)
    at java.io.BufferedInputStream.fill(Unknown Source)
    at java.io.BufferedInputStream.read(Unknown Source)
    at 
org.apache.commons.net.telnet.TelnetInputStream.__read(TelnetInputStream.java:114)
    at 
org.apache.commons.net.telnet.TelnetInputStream.run(TelnetInputStream.java:535)
    at java.lang.Thread.run(Unknown Source)

Any ideas as to what may be happening, how I can fix?

Thanks.

The issue is that this works just fine when not running inside of 
Tomcat. Any ideas what runing inside of a servlet context-spawned thread 
can cause this kind of error?

Well what ever it is has to do with your connecting to
some service/resource and reading something.  Commons
net Telnet connections maybe?  What ever it is is
getting an exception.  I'd start there.  You can also
debug your application.  Develop in an IDE and step
through the code giving you an error.  Netbeans and
Eclipse can help you there.
