IOException: Invalid chunk header

[Aggarwal, Ajay]

I am using standard HTTP 1.1 connector. This is what I see from tomcat output

Ø  INFO [main] 2010-12-22 07:43:03,071 org.apache.coyote.http11.Http11Protocol 
- Initializing Coyote HTTP/1.1 on http-9080

 

And here is the connector configuration element from server.xml

             <Connector port="9080" protocol="HTTP/1.1"

               connectionTimeout="20000"

               />

 

I have a java application that uses HTTP post to stream a large file (50Gb+).  
This large file is received and processed by my servlet running in Tomcat. I am 
seeing following error in tomcat. What could be the possible reasons for this 
error? I have tried googling for this error, but no luck so far.
